About Guéthary
Gu-thary is a renowned, big-wave reef break known as Parlementia, located on the Basque coast of south-western France. The bathymetry consists of a deep-water, terraced rock shelf situated several hundred metres offshore. This geological structure remains dormant during average surf but activates when struck by massive north-westerly winter groundswells from the Atlantic. The wave slowly jacks up from deep water, creating a massive, sloping A-frame that breaks with immense volume rather than a plunging, top-to-bottom barrel. A south-easterly offshore wind is necessary to groom the vast wave face. Due to the extreme size of the wave, the incredibly long paddle out, and the requirement for highly specialized big-wave equipment, Gu-thary is primarily suited for advanced surfers. It demands immense paddle fitness and big-wave experience to catch the fast-moving, thick oceanic swells and execute long, drawn-out carving manoeuvres on the colossal faces.

How often is this page updated?
Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
We compare the 7-day forecast to the last 5 years of marine data for the same week at Guéthary. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late 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.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
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.
