Conditions at Gas Chambers in May
May: Trade-Wind Summer Sets In
May begins the summer lull in earnest. Average swell heights slip to 3-4ft (1-1.1m) and the period drops to 8.7s. The swell direction shifts further into the easterly trades: ENE supplies 37.9%, NE 26.0%, and E 17.5%. Almost all energy is in the 2-3ft (0.5-1m) and 3-5ft (1-1.5m) windows, and there is still virtually no W/SW groundswell. This is short-period trade windswell, not the heavy stuff Gas Chambers really wants.
The good news is that wind is ideal for surfing 64% of the time. Offshore easterlies are lighter, mostly 10-20kph, which means clean little 2-4ft waves. On a shallow reef or ledge, this can still be fun on a longboard or a summer step-up, but it lacks the juice to make the break truly fire. Water temperature is 27.9°C, air averages 26.8°C, and precipitation rises to 4.18mm/day with afternoon tropical showers.
