La 2026 hurricane season in Mexico It is shaping up to be one of the most closely watched in recent years, according to the surveillance and forecasting in MexicoProjections based on records since 1964 indicate that At least five tropical cyclones could directly affect Mexican territory, a figure in line with the historical average but with the added factor of a more unstable climate context.
The preliminary data released by the National Meteorological Service (SMN) and displayed in the 21st International Hurricane SeminarThe meeting held in Mérida indicates that the country will face a challenging season. greater number of systems and potential for intense hurricanes both in the Pacific and Atlantic Oceans. Meanwhile, Civil Protection authorities are refining protocols and developing new early warning tools to reduce risks.
Key dates of the 2026 hurricane season in Mexico
The official hurricane calendar in Mexico is organized by river basin and remains stable year after year, allowing the population to anticipate the period of greatest danger. For 2026, The dates don't change., according to Key dates and namesBut it does meet the level of care recommended by the authorities.
At the Pacific OceanThe season kicks off on May 15th, coinciding with the start of the rainy season in much of the country, while in the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea the beginning is set at the 1 JuneIn both basins, the closure is scheduled for the November 30th, as usual.
The SMN has explained in recent interviews that the The rainy season and the tropical cyclone season are closely linkedThe first tropical systems to form in the Pacific typically mark the start of the rainy season. In fact, the agency predicts that the rains will become widespread around May 15, in line with observed weather patterns.
During the next few months, and especially between June and OctoberThe highest concentration of events is expected, with a surge in tropical activity in midsummer and early autumn, when sea temperatures are higher and the atmosphere becomes more conducive to the development of cyclones.
Before the season officially begins, the SMN and the National Coordination of Civil Protection They will present a detailed forecast of expected cyclones. This calculation, which will be made public between late April and early MayIt will specify the number of storms and hurricanes expected in each basin and will serve as a guide for preventive actions in coastal states.
How many cyclones are expected and what impact could they have?
Preliminary estimates of National Metereological Service And climatology specialists point to a busier season than usualIn total, between the Pacific and Atlantic, the following could form: between 29 and 39 tropical systems, a figure that exceeds the historical average of the last few decades.
For Pacific Ocean the formation of between 15 and 20 tropical cyclones, While in the Ocean Projections place activity between 14 and 19 systemsNot all will reach hurricane strength or approach land, but it is expected that a significant fraction may cause heavy rain, strong gusts of wind and high waves in coastal areas.
Based on climatological records compiled from 1964 to 2025The experts at the National Meteorological Service (SMN) estimate that, on average, Three cyclones per year impact the Pacific coast and two do so on the Atlantic coastFrom this comes the reference figure for 2026: around five tropical cyclones with direct effects on Mexicoeither by impact on land or by its rain bands and winds close to the coast.
However, experts insist that this is a climatological value and not a fixed number. The actual behavior of each season may vary of the average: in 2025, for example, only two hurricanes made landfall in Mexico, well below the average, although the intensity of several offshore systems was remarkable.
Beyond the number of cyclones, the main concern is the intensity that they can reachForecasts indicate that At least four or five cyclones on each coast could evolve into major categories (3, 4 or 5) on the Saffir-Simpson scaleThis poses a considerable risk to critical infrastructure, tourist areas, and coastal communities.
States most exposed and areas of greatest risk
The impact of hurricane season is not evenly distributed along the coastline. Historical data places several states as particularly sensitive areas to the effects of storms and hurricanes that originate in both the Pacific and the Atlantic.
On the slope of Pacific, stand out Baja California Sur and the state of GuerreroThe latter remains under close scrutiny by the authorities after being involved in several separate incidents in recent years. cyclone impacts which have caused significant damage, with recent episodes of high-category hurricanes testing local response capacity.
In the basin of the OceanThe areas of concern are concentrated in Quintana Roo, Yucatán, Veracruz and Tamaulipas, four entities with high exposure to systems that are organized in the Caribbean Sea and the Gulf of MexicoIn addition to its geographical vulnerability, the tourist and economic importance of these areas This makes any injury have amplified consequences.
However, the effects of cyclones are not limited to coastal areas. Rain bands associated with storms and hurricanes They can travel hundreds of kilometers inland, causing floods, landslides, and flash floods in areas far from the point of impact. For this reason, the National Meteorological Service (SMN) and Civil Protection insist that prevention measures must be extended to the entire territory.
In this context, airports and major transport routes They are considered strategic infrastructures, since during an emergency they function as key nodes for the evacuation of people, the transfer of rescue teams and the reception of humanitarian aid.
Influence of El Niño, La Niña and ocean warming
The behavior of the 2026 hurricane season is closely linked to the state of the global climate system, especially to the evolution of phenomena. El Niño y La niña, which alter temperature and atmospheric circulation patterns in the tropical Pacific.
He explained Alejandro Garcia Jimenez, responsible for the Sub-Management of Meteorology and Climate Services of the SMN, Mexico is currently going through a transition phaseThe system is leaving behind the conditions of La niña and is heading towards a scenario dominated by El Niño, with a projected increase in the tropical Pacific Ocean surface temperature during the months of June, July and August.
This change usually translates into increased cyclonic activity in the Pacific and, occasionally, a slight reduction in the formation of systems in the Atlantic. However, experts emphasize that the response is not automatic, since Other factors are involved such as atmospheric pressure, the wind regime at high altitudes, and cloud formation at different levels of the atmosphere.
El Niño has implications not only for the number of cyclones, but also for rainfall patterns and temperatures. It can increase the risk of droughts In some regions, to strengthen the Rain in southern and southeastern Mexico and modify the distribution of intense rainfall episodes, with direct repercussions on sectors such as agriculture, water management and electricity demand.
Given this situation, the SMN maintains a Continuous monitoring of the state of the ocean and the atmosphere to adjust its projections as more information becomes available. Seasonal forecasts will be updated throughout the spring, with particular attention to the summer and autumn period, when the effects of El Niño typically intensify.
Official forecasts and the role of the International Hurricane Seminar
Much of the preliminary information about the 2026 season was presented at the 21st International Hurricane Seminar, a forum where meteorologists, civil protection officials and representatives of public institutions meet to analyze trends and improve preparedness for tropical cyclones.
During the meeting, held in Merida, YucatanThe average impacts based on records between 1964 and 2025, as well as the estimate that Around five tropical cyclones could make landfall in Mexico in 2026Experts stressed that this is a climatological reference point that can fluctuate upwards or downwards depending on how ocean and atmospheric conditions evolve.
The manager of Meteorology and Climatology at the SMN, Rafael Trejo VázquezHe emphasized that the A detailed forecast is still being prepared. and will be formally presented at a meeting with the National Civil Protection Coordination scheduled for April. At that meeting, the expected number of cyclones in both basins will be defined, as well as the risk scenarios for each region.
For its part, Fabian Vazquez RomañaThe general coordinator of the SMN stressed the need for Strengthen prevention measures and the culture of self-protectionRemembering that the combination of climate change, higher sea temperatures and urbanization in vulnerable areas increases exposure to natural disasters.
Among the priorities identified at the seminar were the strengthening of the meteorological monitoring systems, the improvement of the civil protection protocols in coastal states and the updating of evacuation plans and temporary shelters, especially in areas with high population density and tourist activity.
Technology, early warnings, and new monitoring tools
In addition to cyclone forecasts, the SMN is working on the development of new technological tools to improve the monitoring of tropical systems and the dissemination of information to the public in real time. The goal is to reduce the margin of surprise and make it easier for people to make informed decisions well in advance.
One of the standout initiatives for this season is the testing of a mobile phone alert system Specifically designed for phenomena associated with cyclones, similar to the one already used for earthquakes in some regions. This mechanism would allow direct notifications to be sent to users about heavy rains, strong winds, or possible flooding linked to storms and hurricanes.
These alerts would complement the traditional warnings issued by the SMN, the National Water Commission (Conagua) and Civil Protectiondisseminated through media outlets, social networks, and official channels. The intention is for the information to reach people through multiple channels and be clear, timely and easy to understand for any citizen.
At the same time, the numerical prediction models These tools are used to anticipate the trajectory, speed, and intensity of cyclones. Improvements to these tools, supported by data from satellites, ocean buoys, and weather radars, allow for more precise delimitation of potentially affected areas.
All of this is part of a broader strategy of adaptation to increased climate variability and an increase in extreme eventswhich not only affects Mexico, but also other exposed regions of the Atlantic and Pacific, including a large part of the Caribbean basin.
How are tropical cyclones named and what lists will be used in 2026?
One aspect that usually attracts the public's attention every year is the list of names that the cyclones will receiveThe World Meteorological Organization (WMO) manages this naming system, which uses predefined lists sorted alphabetically for each basin and that are rotated in six-year cycles.
A tropical cyclone acquires a proper name when It reaches the category of tropical stormThat is, when it registers sustained winds of at least 63 kilometers per hourBefore that threshold, it is designated with numbers or letters, but does not receive an official name from the list.
In the case of Northeast PacificThe 2026 season will use a roster that begins with Amanda, Boris and Cristinawho will be followed by, among others, Douglas, Elida, Fausto, Geneviev, Hernan, Iselle, Julio and so on until the alphabet is complete. Each name is used only once per season and is not repeated until the list rotates again six years later.
For OceanThe first named cyclone of 2026 will be ArthurFollowed by Bertha, Cristóbal, Dolly, Edouard, Fay, Gonzalo and Hannaamong others. As in the Pacific, the list continues alphabetically up to the letter W, with Wilfred as the last name planned.
When a cyclone causes especially serious damage or a high number of victimsIts name is removed from the list to avoid confusion and negative associations in the future. This is the case, for example, with names replaced after recent seasons in the Caribbean, where very destructive storms led the WMO to incorporate new designations to replace the previous ones.
Recommended prevention measures for the population
Although the most active phase is still some time away, authorities insist that Preparation should begin in advance.Experience from previous seasons shows that a single well-organized cyclone is enough to cause a high-impact event, with significant material damage and social effects.
Among the basic recommendations, Civil Protection suggests have a small emergency storage Pack drinking water, non-perishable food, commonly used medications, and flashlights with spare batteries. These kinds of supplies can make all the difference if the power supply or access to shops is interrupted for several days.
Likewise, the population is asked Follow official reports closely The National Meteorological Service (SMN) and local authorities are consulted, rather than relying on rumors or unverified information circulating on social media. Storm warnings, alerts, and emergency notices are issued well in advance to allow the public to make informed decisions.
Another key indication is Avoid approaching rivers, streams, waterways and coastal areas When heavy rains or storm surges are forecast. Even if the hurricane doesn't make landfall at the exact location where the person lives, the rainbands can generate sudden rises in water levels and very dangerous waves at a great distance from the center of the system.
Finally, experts recommend carefully reviewing the family emergency plans: agree on meeting points, locate the nearest temporary shelters, check the condition of the house and know the evacuation routes defined by the local authorities, especially in neighborhoods located on hillsides, riverbeds or low-lying areas prone to flooding.
Taken together, the information available for 2026 paints a picture active hurricane season marked by the influence of El NiñoWith a higher-than-average number of storms and a significant potential for intense episodes on both Mexican coasts, the forecast is still being refined. Historical averages indicate that around five cyclones could directly affect the country, which, combined with ocean warming and increased exposure in coastal areas, makes prevention, improved alert systems, and heeding official warnings more important than ever.
