About Cape st. Martin reef

Facing, offshore wind, exposure, level and swell range are estimated.

The spot faces NW (306°), so it takes swell from the NW. The wind blows offshore from the SE (126°). It is sheltered to the open swell. It suits intermediate surfers and up. It works in 3–13 ft of swell. The sea floor shelves gently: 10 m deep about 950 m out (1 in 96). On a typical 5 ft, 11 s swell the waves here would spill softly. The sea is about 14°C in May, its coldest month (4/3 wetsuit and boots), and 16°C in January, its warmest (3/2 wetsuit). For intermediate surfers the best months are usually April, May, June and July, with about 1 good days in 7. From the weather of past years. The town to stay in is Saint Helena Bay, 7.5 km away (about 15 min by car). Within 5 km we also list 3 surf spots.

Water about 15°C: 4/3 wetsuit and boots. Typical sea temperature for the time of year, not a forecast.

The score is the conditions only: the journey, the price and the partners never change it (how we score, how we earn).
