Climate averages by month for any place
Thirty years of daily data (1996–2025) boiled down to what each month is really like: average high and low, rainfall, rainy days, sunshine and snow. Then see which months suit your trip.

What “climate average” means here
Weather is one day; climate is the pattern over many. Meteorological services define “normals” as 30-year averages (the World Meteorological Organization currently uses 1991–2020). We use the latest complete 30 years, 1996–2025, from the ERA5 reanalysis, so every place on Earth gets numbers built the same way, including places with no station.
Average high is the mean of every daily maximum in that month across 30 years; precipitation is the mean monthly total; days ≥1 mm counts days with at least a millimetre of rain or melted snow, the threshold national weather services use for a “rain day”. Averages hide spread: a month with a 20 °C average high can still bring 12 °C days. For a specific date, check the event-date odds, which show the range.
Questions people ask
Which years are the averages based on?
The 30 complete years 1996 to 2025, taken from ERA5 reanalysis through the Open-Meteo archive.
Why do these numbers differ from official climate normals?
Official normals use a station’s own thermometer and usually the 1991–2020 period. Reanalysis describes a grid cell several kilometres wide, so coastal, mountain and city-centre sites can differ by a degree or two.
How is the best time to visit worked out?
Each month gets a 0–10 score from how well its average high fits your chosen range, how many rainy days it has and how many sunshine hours. The formula is shown on the page; it ignores prices and crowds.
What counts as a rainy day?
A day with at least 1 mm of precipitation, the usual threshold used by national weather services.
