How the score works
Every spot gets a composite score out of 10 using a multiplicative penalty chain. The wave height base is multiplied by each factor, then safety-capped, then a dawn/dusk bonus is added.
Sweet spot is 0.7 to 1.2m. Below 0.3m is marginal. Above 2.5m is dangerous due to wipeout forces on the mast.
Foils extract energy from disorganised swell. Short-period wind swell loses only 16% vs 57% for surfing. Small groundswell bonus above 11s.
Foils ride above surface chop, so onshore wind barely matters. Only penalises above 15 km/h, and even then gently.
Low tide over shallow reef is dangerous for foils (mast strike risk). Reef, point, and beach breaks each have different risk profiles.
Frequently asked questions
How often is this updated?
Every 6 hours when the conditions cron runs. We pull fresh swell, wind, tide, and visibility data for every spot and recalculate the foil score.
How is the foil score calculated?
A multiplicative penalty chain: wave height base (0-10) multiplied by period, swell direction, wind speed, gust consistency, wind direction, tide safety, current, rain, and visibility factors. Safety caps prevent inflated scores in dangerous conditions. A dawn/dusk glassy bonus rewards glass-off sessions.
Why do foil scores invert from surf scores?
Foils generate lift from minimal swell energy. A 0.5m choppy day scores 2/10 for surf but 5/10 for foiling. Conversely, a 2.5m clean day scores 8/10 for surf but only 2/10 for foiling (too dangerous with a mast).
What types of foiling does this cover?
Surf foiling (prone and SUP), wing foiling, and pump foiling. The scoring formula optimises for the overlapping conditions that suit all foil disciplines.
Where does the data come from?
Open-Meteo Marine and Weather APIs. Swell height, period, direction, wind, visibility, and precipitation for every spot. Tide position from harmonic predictions.
Are these the same spots as the surf leaderboard?
Yes, the same 260 surf spots ranked by a completely different formula. The days most surfers skip are often the best foiling days.
