About Thermopylae

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

The spot faces NW (310°), so it takes swell from the NW. The wind blows offshore from the SE (130°). It is sheltered to the open swell. It suits intermediate surfers and up. It works in 5–20 ft of swell. The sea floor shelves moderately: 10 m deep about 250 m out (1 in 23). On a typical 5 ft, 11 s swell the waves here would crumble. 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). The town to stay in is Cape Town, 3.4 km away (about 10 min by car). Within 5 km we also list 7 surf spots, 2 wind sports spots and 4 dive sites.

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).
