About Backwash

Facing, offshore wind, exposure, level and swell range are estimated. Facts: verified, surf details estimated.

The spot faces SE (117°), so it takes swell from the SE. The wind blows offshore from the NW (297°). It is sheltered to the open swell. It suits intermediate surfers and up, because of a steep sea floor. It works in 3–12 ft of swell. The sea floor shelves very steeply: 10 m deep about 50 m out (1 in 7). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 28°C in October, its coldest month (no wetsuit), and 30°C in February, its warmest (no wetsuit). For intermediate surfers the best months are usually May, June and September, with about 5 good days in 7; in January, February and December, about 1. From the weather of past years. No town nearby. No stay checked for this site yet: Zancudo, 22 km away, is the nearest town we list. Within 5 km we also list 2 surf spots.

Water about 28°C: no wetsuit. Typical sea temperature for the time of year, not a forecast.

Day scores here are the conditions out of 80; a trip's score on the results is the same conditions out of 100. The journey never scores. The forecast reaches about 10 days. Energy is the swell's power in kJ per metre of wave, from its height and interval: it grows with the square of each, so a long-period swell hits far harder than a short one the same size. The word under the swell is the wave's shape, our estimate from the sea floor. Wind is in knots: 10 kn is about 19 km/h. The arrow points where the wind blows to; offshore wind, blowing from the land out to sea, is green and says so.
