How we know thisConfidence low

Confidence. Lake or river spot: global weather models underestimate local thermal winds here.

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.

Best months: at least half the days are kite days (50 % or more), outside the cold months. The colours grade every month on their own scale: Prime from 60 %, Good from 40 %, Possible from 20 %.

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.
