About Big River

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

The spot faces SW (231°), so it takes swell from the SW. The wind blows offshore from the NE (51°). It is sheltered to the open swell. It suits intermediate surfers and up, because of a steep sea floor. It works in 5–20 ft of swell. The sea floor shelves steeply: 10 m deep about 100 m out (1 in 11). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 11°C in February, its coldest month (4/3 or 5/4, boots and gloves), and 14°C in September, its warmest (4/3 wetsuit and boots). The town to stay in is Mendocino, 0.1 km away (about 5 min by car).

Water about 13°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).
