ClimaAtlas shows the best time to visit any destination based on real, long-term climate data — not a weather forecast, but statistical averages that tell you what to expect in a typical month. It is built on established scientific data sources, so the numbers behind every recommendation are transparent and verifiable.
Temperature, rainfall, humidity, and solar data are based on the ERA5 reanalysis by the ECMWF (European Centre for Medium-Range Weather Forecasts / Copernicus), blended with station measurements. Sea-surface temperatures come from the Copernicus Marine Service (CMEMS). These are among the most widely used and peer-reviewed climate datasets available.
All values are monthly averages over roughly 20 years (2005–2025) — long enough to smooth out individual outlier years and reveal the typical climate of each month. Sunshine hours are computed with the Ångström-Prescott formula (FAO-56) from solar-radiation data, which is more accurate than raw reanalysis estimates. Rain days count days with measurable precipitation.
To turn raw numbers into a plain-language verdict, ClimaAtlas rates each month with a KlimaScore that combines sunshine, temperature comfort (closeness to a pleasant range), and low rainfall. The months with the best balance become the recommended best travel time — so you get an answer, not just a table to interpret.
ClimaAtlas is not a weather forecast. Climate data describe the typical long-term average — any single year, week, or day can differ. Use it to plan which month to travel, then check a live forecast close to your trip.
