La 2025 Atlantic hurricane season has come to an end with a balance as striking as it is paradoxical: activity within the expected values in total number of systems, according to analysis of the average activity in the basin, but with a unusually high proportion of very intense hurricanes And, at the same time, without a single direct hurricane impact in the United States. For the basin as a whole, the period has yielded figures that fall within climate averages, but also extreme events that have broken historical records.
Globally, meteorologists point out that It was a "strange" season and difficult to fit into classic patternsThere were fewer hurricanes than initially predicted, but most reached high categories and generated a cumulative cyclonic energy clearly exceeding what would be expected with so few systems. Furthermore, atmospheric behavior diverted a large portion of the cyclones toward the open ocean or the Caribbean, reducing the direct impact on the North American continent but exacerbating the consequences for several islands—a situation that NOAA had anticipated in their general forecasts.
Overall tally: 13 named storms and disproportionate intensity
They formed in the Atlantic 13 named storms between June 1 and November 30exactly within the mid-range of what is considered normal for the recent climatological series, a fact that coincides with analyses on the Atlantic hurricane season. Of them, Five reached hurricane status and four reached major hurricane status (category 3 or higher), a figure that exceeds the historical average of three intense hurricanes per season.
The United States National Oceanic and Atmospheric Administration (NOAA) had anticipated a slightly above-normal season, with between 13 and 19 named storms and between 6 and 10 hurricanes, several of which could be of great intensity. The forecast was accurate regarding the level of energy released by the cyclones.But not in the classic distribution between number of systems and strength: there were fewer hurricanes than expected, although almost all of them behaved like true "heavyweights".
The named storms include Andrea, Barry, Chantal, Dexter, Fernand, JerryKaren and Lorenzo like cyclones that did not reach maximum intensity, and Erin, Gabrielle, Humberto, Imelda and Melissa as hurricanes. Of these, four were classified as major, and three reached category 5, the highest level on the Saffir-Simpson scale.
The season also saw a a very noticeable pause during the most climatically active weeksBetween the end of August and mid-September, the Atlantic remained virtually silent. This lull contrasts sharply with the intense final stretch of October, dominated by the rapid intensification of Melissa, which concentrated many of the year's most severe impacts—a phenomenon that connects with the impact of tropical storms in vulnerable regions.
A year without hurricanes in the United States, but devastating for the Caribbean
One of the most talked-about facts of this season is that, For the first time in a decade, no hurricane made landfall on the continental United States.The only named storm that made landfall was Tropical Storm Chantal, which entered in July through the Carolinas with relatively modest winds and caused localized flooding and some fatalities, but without reaching hurricane status.
According to the NOAA administrator, Neil jacobsThis respite was "a much-needed break" for a country that had just come through a decade with more than two dozen hurricane impacts. However, the absence of direct impacts in the United States does not translate into a benign season.Several cyclones caused strong waves, storm surges and rip currents that damaged coastal infrastructure on the east coast, while the most severe effects were concentrated in neighboring Caribbean nations.
Experts link this pattern of trajectories to anomalies in atmospheric circulation and changes in high-altitude windsThese factors, related in part to Arctic warming and the jet stream's orientation, would have caused many cyclones to recurve eastward or remain further south, avoiding the typical direct route to Florida or the Gulf of Mexico, but fully exposing countries like Jamaica, Haiti, and Cuba, as shown in analyses of Risks and challenges in Florida and the Caribbean.
En Europe and the eastern Atlantic coastThe remnants of several storms resulted mainly in episodes of high waves, swells, and some rainfall associated with extratropical systems, without amounting to a direct hurricane impact. Regions such as the Azores and parts of the northeastern Atlantic saw some of these systems pass by at a distance, transformed into mid-latitude low-pressure systems.
Erin, Humberto and Imelda: powerful but mostly oceanic hurricanes
Within the list of hurricanes for the season, Erin He was the first to reach category 5 and one of the cases of rapid intensification more extremes never before documented in the Atlantic. In just 24 hours, it went from a Category 1 hurricane, with winds of about 120 km/h, to a Category 5 cyclone with winds close to 260 km/h, and also registered one of the fastest drops in atmospheric pressure in a single day in the basin, a symptom of increasingly powerful hurricanes.
Despite his strength, Erin mostly stayed at sea.generating strong waves and rip currents along the east coast of the United States and affecting navigation, but without a direct impact on large populated areas. Similar situations occurred with Humberto e Imelda, which reached or approached major hurricane intensity but ended up recurving away from the continent thanks to unusual wind patterns.
Meteorologists emphasize that This combination of very powerful cyclones and relatively benign trajectories for the United States This should not be confused with a sign of lower long-term risk. The season fits into a broader trend in which the Atlantic has now experienced nine of the last ten above-average hurricane seasons, driven by exceptionally warm ocean temperatures and patterns like La Niña in the Pacific, which tend to favor hurricane development in the Atlantic basin.
The behavior of these systems also produced some curious episodes, such as the close interaction between Humberto and Imelda, which came closer to each other than any other pair of hurricanes observed with reliable satellite data, or trajectory deviations attributed to the so-called fujiwhara effectwhere a large hurricane modifies the movement of another, weaker cyclone located around it.
Even with these unexpected twists, the final balance confirms that the Most of the human and economic damage was concentrated in the Caribbean islands and Central AmericaWhile the US East Coast and Gulf experienced an unusually quiet year compared to what had been the norm since 2015, and the need for the Civil protection intensify actions It became especially clear.
Melissa: a record-breaking hurricane that marked the season
If there's one name that sums up the 2025 hurricane season, it's MelissaThis cyclone reached the Category 5 with estimated winds of up to 295 km/h and became one of the most intense hurricanes ever recorded in the Atlantic. The World Meteorological Organization has called it the "storm of the century" for Jamaica, and subsequent analyses rank it as the third most powerful cyclone to ever make landfall in the history of the Atlantic basin.
The hurricane formed in the Caribbean in late October and experienced exceptional rapid intensificationIt intensified from a tropical storm to a very high-category hurricane in less than three days, as it moved slowly south of Jamaica over unusually warm waters. This slow trajectory sustained torrential rains and extreme winds for days over a relatively small area of the western Caribbean.
When Melissa hit the West Jamaica on October 28It did so with sustained winds of around 185 mph (about 295 km/h), matching historical records such as that of the 1935 Labor Day Hurricane. A probe launched by NOAA hurricane hunter aircraft inside the eyewall measured a gust of about 252 mph (more than 400 km/h) at low altitude, now considered the highest wind speed recorded directly in a tropical cyclone.
After crossing Jamaica, Melissa continued to affect Haiti, eastern Cuba, and other areas of the Caribbean.Despite strong winds and a massive influx of moisture, floods, landslides, and infrastructure destruction spread across much of the region, particularly affecting rural and coastal areas already vulnerable to the elements.
The human and economic toll is devastating: it is estimated More than a hundred deaths, mainly in Jamaica and Haitiand damages that various organizations and analysis centers, such as AccuWeather's Global Climate Center, estimate at tens of billions of dollars. In Jamaica alone, some preliminary assessments have placed the losses at over $10.000 billion, while other regional estimates raise the total cost of the catastrophe to more than $48.000 billion.
Impacts in Central America and the Eastern Atlantic
Although media attention focused on the direct impact on Jamaica and Haiti, Other areas of the Caribbean and Central America also suffered indirectly during the seasonHurricane-force winds and extremely rough seas associated with Melissa affected parts of Cuba, the Dominican Republic, and Panama, where significant property damage and prolonged outages of basic services were reported.
En Costa RicaFor example, Hurricane Melissa did not make landfall, but its presence in the western Caribbean had a clear impact on the weather. The National Meteorological Institute (IMN) considers the season in the region to be... It remained within normal ranges in the number of systemswith 12 named cyclones that influenced its surroundings in one way or another. However, the circulation associated with Melissa significantly activated the Intertropical Convergence Zone and triggered record rainfall during the month of October.
Several Costa Rican weather stations recorded their rainiest October on record, with total rainfall that They far exceeded 500 mm in Pacific and inland locations. Names like Nicoya, Parrita, San Pedro, Alajuela, Liberia, Puntarenas or Quepos These are among the places where monthly rainfall broke records, reflecting how a hurricane located hundreds of kilometers away can completely reorganize a country's rainfall pattern.
The IMN emphasizes that, despite the intensity of some rain episodesThe season ended for Costa Rica with relatively contained impacts compared to other, much more active years. The agency highlights the role of climate variability and certain atmospheric patterns which, even with surface conditions similar to those of very intense seasons, resulted in a moderate number of storms in 2025, but one heavily influenced by one or two extremely powerful systems.
At the Eastern Atlantic and areas closer to EuropeThe consequences have been even more indirect, resulting in swells, coastal storms, and the passage of low-pressure systems that originated as tropical or subtropical cyclones. These types of interactions serve as a reminder that, although hurricanes do not usually reach the Iberian Peninsula or the European continent with their tropical structure intact, they can influence the dynamics of autumn storms that affect Spain and other surrounding countries.
A "strange" season: a pause at the peak and a late rebound
Tropical climatology specialists agree that 2025 will be remembered as an atypical yearIn addition to the striking intensity figures, there is an unusual temporal behavior: after a relatively active start in June and July, the basin experienced around three weeks practically without any rainfall during the peak climatological period, from the end of August to the middle of September.
This type of shutdown in the middle of peak season is not unprecedented, but it is very infrequent. Preliminary analyses point to a combination of Dry air in the eastern Atlantic, Saharan dust, and unfavorable wind shear patterns so that the tropical waves coming out of Africa could organize into well-defined cyclones. The result was a surprisingly calm period, even though sea surface temperatures continued to show values well above average.
The calm, however, did not last. From the second half of September and, above all, in October, the atmosphere changed and The season was concentrated into an intense final stretchMuch of the year's accumulated cyclonic energy was generated in those last six weeks, which saw most of the high-category hurricanes, including Melissa's climb to category 5.
This back-and-forth has led several researchers to insist that, In a warming climate, it is not enough to simply count the number of storms.It is becoming increasingly important how they are distributed over time, what intensity they reach and what paths they follow, since even a season with a "normal" number of cyclones can lead to unprecedented impacts if just one of them coincides with populated and vulnerable areas.
For Europe, and in particular for Spain, these types of seasons confirm the need to closely monitor the evolution of hurricanes and their remnantsEspecially in autumn, when ex-hurricanes can integrate into the polar jet stream and trigger storms of rain and wind with notable effects on the Atlantic coast, although without the violence typical of a tropical cyclone in its mature phase.
Artificial Intelligence models and improved forecasting
Another relevant element of this season has been the qualitative leap in the forecasting methods. For the first time, the NOAA's National Hurricane Center (NHC) has operationally incorporated models based on Artificial Intelligence in their forecasts of trajectory and intensity. These tools, trained with large databases of past cyclones and atmospheric conditions, have been used as an additional guide alongside traditional numerical models.
According to NHC officials, the combination of both approaches allowed anticipate, several days in advance, the rapid intensification of some of the most dangerous hurricanesincluding Melissa. In the specific case of this cyclone, the US center was able to project with great accuracy the trajectory that would lead it to impact Jamaica, reducing the final deviation to just a few tens of kilometers from the route predicted several days earlier.
Researchers who have analyzed the performance of the models during the season indicate that AI algorithms have competed head-to-head with some of the most established prediction systems.both in trajectory and intensity. Although there is still a way to go to fully integrate them into daily operations, the 2025 results are considered a clear indication of their potential to improve the anticipation of extreme events.
Looking ahead to Europe, this improvement in the forecasts It is especially relevant for tracking former hurricanes that could rejoin the jet stream and affect the weather in the northeastern Atlantic. Having more precise trajectories helps to better assess the risks of strong swells, heavy rain, or winds associated with tropical storms that sometimes reach the Iberian Peninsula or the western part of the continent.
Against the backdrop of climate changeThe scientific community insists that each hurricane season should be understood not just as a set of statistics, but as one more piece of a larger puzzle in which sea surface temperatures, global atmospheric patterns, and natural variability combine to produce increasingly complex scenarios. The season that has just ended leaves a mixture of relief in some regions and devastation in others, and reinforces the sense that planning and adaptation will be key in the years to come.
With the official end of the hurricane season, the Atlantic basin enters a phase of apparent calm, but the experience of 2025 shows that A year can be considered climatologically "normal" and still register record-breaking hurricanes and extraordinary damage in specific areas.For countries in the basin, from the Caribbean to Western Europe, the lesson this season leaves is clear: rather than focusing solely on the number of storms, it is important to pay attention to how, where, and with what intensity they develop.
