What modelled windy, riders' months and no series mean
modelled windy
The modelled series at one of the destination's spots puts December at half its days or more with three or more hours over 12 knots. That share is enough on its own: a spot here may or may not also name December among its best months.
riders' months
A spot names December among its best months while the model reads under half. Both figures are drawn and neither is adjusted.
no series
No spot at the destination carries a usable modelled series, so the months are the ones riders and schools name.
Modelled windy in December
3 destinations
A spot's modelled series reaches 50% of December days or more. That share is enough on its own: a destination here may or may not also have a spot naming December among its best months.

How this list is ordered, and what puts a destination on it
Ordered by the modelled share of windy days in December where a spot carries a series (3 of 3 here); where a destination groups several spots, the share shown is the best of them, and the spot it was modelled at is printed under the figure on every card.
