Confidence

Confidence highhourly model data, close sea cell, checks agree on the season

Why. Hourly model data, 2017 to 2025, checked against the season shape of a nearby weather station, a regional model or a documented season.

What it means for you. The numbers on this page are a fair forecast of a typical year here. Medium would mean one check is uncertain, for example a cell 12 km away: expect a few points off. Low means global models miss part of the local wind, often at lakes, thermal or inland spots; where documented local sources describe the season, we show that curated season instead of model numbers.

Water and wetsuit

25 °C in October, spring suit (21 to 23 °C).

The air is cool for this water, so we add one step.

Where the model is blind

Here the model sees the wind at Marmari, Kos, so the numbers on this page are model numbers. Where documented local sources describe the season of a lake or thermal spot, we show that curated season instead: a hatched band over the season months with its sources named and no percentage, because the model number would be wrong there.
