About Porthmeor
Porthmeor is a highly scenic, semi-sheltered beach break situated in the town of St Ives on the north coast of Cornwall, United Kingdom. The bathymetry features an expanse of highly compacted, pristine sand enclosed between two prominent rocky headlands. Because the beach faces north, it heavily filters the extreme violence of raw westerly Atlantic winter storms, allowing more organised, moderate swell energy to enter the bay. The location operates optimally on a north-westerly groundswell paired with a southerly offshore wind. The gradual sandy gradient ensures the waves break with a workable profile, generating highly manageable A-frame peaks offering both left and right-hand rides. The forgiving mechanics, combined with the structural protection from extreme weather, make Porthmeor highly suitable for intermediate surfers. It provides predictable walls for carving manoeuvres, serving as an excellent, consistent urban training ground when fully exposed regional beaches are overloaded by heavy swell.

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 Porthmeor. 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.
