About Seal Rocks, Treachery
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces S (170°), so it takes swell from the S. The wind blows offshore from the N (350°). It is exposed to the open swell. It suits intermediate surfers and up. It works in 2–10 ft of swell. The sea floor shelves moderately: 10 m deep about 300 m out (1 in 30). On a typical 5 ft, 11 s swell the waves here would crumble. The sea is about 20°C in July, its coldest month (2 mm shorty), and 25°C in January, its warmest (no wetsuit). The town to stay in is Seal Rocks, 2.3 km away (about 5 min by car). Within 5 km we also list 7 surf spots.
Water about 22°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
