How often is this page updated?
Current conditions refresh every morning at 06:00 UTC from the daily snapshot. The 7-day forecast caches for 6 hours, and the historical baseline for this calendar week refreshes weekly.
What is the luck factor?
We run the same scoring algorithm on this week's 7-day forecast and on the average of the last 5 years for the same calendar week. The delta tells you whether Mentawai Islands is shaping up better, worse, or about the same as a typical mid-April.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer. Think of it as the day most likely to be worth driving to the beach.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions). The same models power many surf forecast apps.
Does the score capture local knowledge?
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.
