Conditions at Sayulita in May
May: Long Period, Wrong Direction
May keeps the average swell at 1.1m (3.6ft) with a very long 14.0s period, but the direction is now firmly in the southern quadrant. WSW contributes 46.0%, SW 43.3%, and SSW adds 1.4%, leaving only 0.4% from true WNW. This is the classic southern-hemisphere / early tropical swell signature, and it does not align well with Sayulita's NNW exposure. The bay can catch some of the W/WSW energy, but wave quality tends to be average and inconsistent. Wind is still trapped in the N-NNW regime, with NNW at 30.9%, NW at 23.7%, WNW at 18.3%, and N at 7.5%. Ideal offshore wind remains rare at 3%. Water temperature warms to 26.9 degrees C, air averages 26.2 degrees C, and precipitation is still low at 0.28mm/day. If you score a clean glassy morning, expect 2-4ft (0.6-1.2m) sea-swell mix rather than powerful winter walls.
