About Bull Bay
Bull Bay, officially known as Copa, is a prominent reef and point break situated on the south-eastern coast of Jamaica. The geomorphology features a rounded cobblestone and coral rubble shoreline that transitions into a shallow, uneven reef shelf. The wave dynamics rely upon short-to-medium period south-easterly wind swells generated by the Caribbean trade winds. When groomed by a northerly offshore wind descending from the nearby Blue Mountains, the wave refracts around the cobblestone point, creating a steep, peeling right-hander. The take-off is frequently rapid, dropping over a shallow section of the reef before spilling into a deeper, slower-moving inside section. Because the wave requires precise positioning near the rocky outcrop and breaks over an unforgiving bottom, it is best suited for intermediate to advanced surfers. The wave offers workable walls for carving manoeuvres and occasional short tube sections, but demands constant vigilance regarding water depth and the sharp coral structure below.

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 Bull 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.
