About Diablo Deck - San Luis Obispo
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SW (225°), so it takes swell from the SW. The wind blows offshore from the NE (45°). It is sheltered to the open swell. It suits intermediate surfers and up. It works in 2–9 ft of swell. The sea floor shelves steeply: 10 m deep about 150 m out (1 in 13). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 12°C in May, its coldest month (4/3 or 5/4, boots and gloves), and 16°C in September, its warmest (3/2 wetsuit). For intermediate surfers the best months are usually August and September, with about 3 good days in 7. From the weather of past years. The town to stay in is Los Osos.
Water about 15°C: 4/3 wetsuit and boots. Typical sea temperature for the time of year, not a forecast.
