Olatu: Surf forecasts for the Basque coast
Your daily surf check for the Basque coast. Personalized ratings, swell, wind, tides, water quality and live webcams, all in one fast, clean app.
Everything you check before a surf, in one place
• Hour-by-hour swell: height, period, and direction
• Wind speed and direction, with onshore/offshore at a glance
• Full tide charts with high/low times and sunrise/sunset
• Water quality so you know when to stay out after rain
• Live webcams to see the real conditions before you drive
Forecasts that know your level
Every spot gets a personalized surf rating that weighs swell size and direction, period, wind, and tide against what each break actually needs, and against the kind of surfer you are. Set your level and Olatu tells you where it's worth paddling out today, not just what the raw numbers say.
Your surf log, smarter forecasts
Log and rate your surfs. It's your surf diary, and it teaches Olatu what you love, so smart alerts ping you when the forecast matches your best days. Or set your own thresholds with classic alerts.
