Typical weather, not a forecast: averages for 2021–2025 (air, rain, wind), data from Open-Meteo (ERA5 / Copernicus, Météo-France). Covers an area of roughly 10 to 25 km around the destination.
Åland's season runs from late March or early April (depending on ice) to mid-December; surface water peaks at 18–20 °C in July. Diving in Finland is possible year-round, with ice diving in winter (PADI Travel).
From the easiest to the most demanding. Levels with a dashed outline are estimates we are still verifying.
