AnyWeather calculated these monthly values from daily ERA5 reanalysis data for 1991-2020, retrieved through the Open-Meteo Historical Weather API. ERA5 is gridded model-and-observation reanalysis, not a reading from a city-center weather station. Coastlines, elevation, urban heat, and local storms can produce meaningful differences.

Coastal humidity, sea breezes, and urban heat mean the beach, waterfront, and inland neighborhoods may not feel the same even when the displayed air temperature is similar.
- Beach plans
- Check wind, UV, rain, and official coastal information rather than relying on temperature alone.
- Hot weather
- Humidity can raise heat stress; schedule exposed walks outside the hottest period and carry water.
- Storm days
- Short, intense rain can disrupt low-lying streets and transport, so review warnings before departure.
What to watch
Heat, coastal wind, thunderstorms, and intense rain are the main planning signals. AEMET warnings should take priority over a general app forecast.
