Conditions at Killer Point in May
May: Summer Pattern Takes Root
May is when the low surf season begins in earnest. Average swell height drops to 1.8m (5.9ft) and the average period falls to 9.4s, now more average and punchy than powerful and long-period. The swell direction is heavily locked into the NNW, which accounts for 62.9% of the waves, while NW drops to 19.3%. This is a predominantly short-period, windswell-influenced regime, although the 1.5-2m and 2-2.5m distributions still produce fun, rippable waves on the better days.
Winds become the limiting factor. The ideal offshore window shrinks to just 19%, while NNW winds total 37.0% and NW 24.4%. This means the beach is blown out much more frequently. Air temperatures warm to 19.4°C, water temp climbs to 17.4°C, and precipitation nearly vanishes at 0.28mm/day. May is not a write-off, but only the early mornings or the rare easterly offshore windows will deliver Killer Point at its best.
