Alnon / Stornaset
Kite days peak in August at 47 %.
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 lowSeveral checks are uncertain here: a distant model cell, models that disagree on the season, or a failed reference test. Global weather models underestimate local thermal winds at lakes, gorges and some coasts.
