Based on historical weekly averages
Combining historical conditions with school holiday crowd pressure to find the sweet spot.
How busy each week is based on school holiday overlap from feeder markets.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.

Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
The best week for surf at Somo is the week of 16 November (score 3/5) with low crowds.
Slim pickings. Only worth it if you are gagging for a wave. Strong offshore, clean but tough to paddle into.
Heads up: jellyfish: high.
