In the same range are other cities such as Phoenix (Arizona), which records nearly 3.872 hours of sunshine per year, which translates to an average of about 300 clear days a year.
In these cities, extreme heat accompanies intense sunPhoenix, for example, exceeds 38°C (89°F) for about 50 days a year, reaching historic highs of up to XNUMX°C (XNUMX°F). So, it's not all beach and caipirinha: living in these destinations has its pros and cons.
Which European city enjoys the most hours of sunshine?
On the European scene, Spain dominates the spotlight when it comes to sunshine. According to recent studies by World Weather Online and analyses by major travel sites like Holidu, the list of Europe's sunniest cities is dominated primarily by Spanish destinations. The data was obtained by averaging monthly sunshine hours from 2009 to at least 2025 in the most populated cities.
Alicante tops the European list, with an average of 349 hours of sunshine per month. (about 4.200 hours per year). Close behind are Cartagena, Murcia, Malaga, Valencia, Las Palmas, Granada, and Seville. This solar supremacy makes Spain a favorite destination for those escaping the dreary days.
Top 10 sunniest cities in Europe: facts and figures
The last decade has consolidated this ranking of European cities with the most hours of sunshine:
- Alicante – Spain: 349 hours/month on average.
- Catania – Italy: 347 hours/month.
- Murcia – Spain: 346 hours/month.
- Malaga – Spain: 345 hours/month.
- Messina – Italy: 345 hours/month.
- Valencia – Spain: 343 hours/month.
- Nice – France: 342 hours/month.
- Las Palmas – Spain: 341 hours/month.
- Granada – Spain: 341 hours/month.
- Palermo – Italy and Seville – Spain: 340 hours/month.
These data reflect that in many cases The south and east of the Iberian Peninsula are true paradises for sun lovers.However, hours of sunshine don't always mean high temperatures: Granada and Nice, despite their high levels of sunshine, have the lowest average temperatures in this ranking.
Spain's solar supremacy: beyond Alicante
Spain not only leads the ranking by cities, but the Most of its provinces easily exceed 2.500 hours of sunshine per yearThe territory itself, divided between the peninsula, the Balearic Islands, and the Canary Islands, offers a variety of microclimates and a wide range of clear days.
It's not just the main cities that are bright. For example, Huelva is the sunniest city in the country, according to some records, with more than 3.500 hours of sunshine per year. Even at the other extreme, like Bilbao, the figure remains remarkable, with 1.694 hours per year.
Annual hours of sunshine in Spain by province
- Andalusia: Huelva (3.527 h), Seville (3.526 h), Cadiz and Cordoba (3.316 h), Almeria (3.305 h), and Malaga (3.248 h) stand out.
- Valencian Community: Alicante (3.397 h), CastellĂłn (3.321 h), Valencia (2.808 h).
- Murcia: Murcia capital adds 3.348 hours per year.
- Estremadura: Badajoz (3.224 h), Cáceres (3.365 h).
- Catalonia: Lleida (3.031 h), Tarragona (2.820 h), Barcelona (2.453 h), Girona (2.800 h).
- Castilla la Mancha: Albacete (3.282 h), Ciudad Real (3.295 h).
- Canary Islands and Balearic Islands: Between 2.800 and 3.098 hours per year depending on the island.
- Galicia, Asturias, Cantabria and the Basque Country: They range between 1.639 and 2.820 hours, being the regions with the least sunshine.
These data show that the enormous variability of sunshine hours depending on location and geographical conditionsAltitude, proximity to the sea, and mountain orientation have a decisive influence, giving rise to differences even within the same autonomous community.
What is Peak Sun Time (PSH) and what is it used for?
Peak Sun Hour is a fundamental concept for those who want to install solar panels on their homes or businesses. It is a unit of measurement that reflects the amount of solar energy that falls on a surface during one hour under ideal radiation conditions: 1.000W/m² per hour.
In practice, this data allows us to calculate the actual production capacity of a solar installation, adjusting the size of the system to the needs of each user based on their province.
When are there more hours of sunshine? The importance of the seasons
The number of hours of sunshine varies throughout the year depending on the season. In summer, the days are longer and the Earth's tilt relative to the sun allows for greater sunshine, especially around the June solstice., when the period of maximum exposure is reached.
In winter, the opposite occurs: the days become shorter and the angle of sunlight decreases, reducing the amount of useful light, especially in the northernmost provinces. Therefore, The season of the year greatly influences energy production and the general atmosphere of the place..
The role of solar energy in a sun-drenched country
Spain has become a European benchmark in the installation of solar panels, and with good reason: the abundance of hours of sunshine makes investment in photovoltaic energy especially profitable. In most provinces. All regions, from Andalusia to Galicia, have sufficient solar radiation to justify self-consumption installations.
This has led to the existence of numerous aids, bonuses and subsidies, both state and regional and municipal, aimed at promoting the transition towards a more sustainable model and reducing the payback period of the initial investment.
The sun as part of life and culture
Beyond the facts, sun-drenched cities have a special atmosphere. Natural light transforms the way of life, architecture, customs, and even the mood of its inhabitants. Cities in the ranking, such as Alicante, Murcia, Málaga, and Cartagena, not only lead the way in terms of numbers, but also encourage people to enjoy a healthier and more active lifestyle.
So whether you're planning to move, travel, or invest in solar energy, Taking into account the hours of sunshine in each destination can make a difference.Southern and eastern Spain take the cake, but virtually every part of the country offers more sunshine than the European average.
As a culmination, Choosing the city with the most hours of sunshine will allow you to enjoy a vibrant, healthy and, in many cases, more energy-efficient environment.Spain, with its undisputed leadership in sunshine, offers an extraordinary variety of destinations where the sun plays a central role in everyday life.
