Groos
Best for kiting from May to October, with 58 to 66 % kite days. Water 12 to 18 °C. Also windy, but cold (water and air under 12 °C or short days): November to April.
A kite day has at least 3 hours of 12 to 35 knots (gusts up to 45) between 10:00 and 19:00, in daylight. Percentages are the share of such days in each month, counted over 9 years.
- Prime 60 % and more
- Good 40 to 59 %
- Possible 20 to 39 %
- Off under 20 %
- No data hatched
- Ringed: this month
Prime also needs a good month in at least 7 of the 9 years, so one freak year cannot make a month Prime. A month with 60 %+ but fewer good years shows as Good.
Confidence highHourly model data, 2017 to 2025, checked against the season shape of a nearby weather station, a regional model or a documented season.
