About Constantine Bay
Constantine Bay is a powerful, highly dynamic beach and reef break located on the north coast of Cornwall. The seafloor is a treacherous mixture of mobile sandbanks heavily interspersed with sharp, underlying rock ledges. When struck by a solid westerly Atlantic groundswell, this uneven bathymetry forces the waves to jack abruptly, producing fast, heavy, and frequently hollow A-frame peaks. An easterly offshore wind is necessary to smooth the aggressive wave faces. Due to the rapid take-offs, the severe consequence of the exposed rock at low tide, and the formidable rip currents that sweep across the bay, Constantine is strictly an advanced surfing location. It demands rapid, decisive actions and the technical ability to navigate steep drops and high-speed sections before the waves close out violently onto the sandbars. The intense rip currents necessitate robust physical endurance and elite spatial awareness.

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 Constantine Bay. 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.
