Conditions at Golf Course Reef in May
May: Southern Ocean Power with Offshore Grooming
May marks the beginning of the true winter season. Average wave height is 6ft (1.8m), period lengthens to 9.3s, and ideal wind climbs to 59%. Most of the swell now comes from S, SSE and SE rather than the pure NE/E quadrant, but the presence of strong W/WNW offshore winds means the waves are organized, clean and powerful. This is where an east-facing reef can handle a less direct swell angle because the wind is working with the break.
Air temp drops to 16.8°C and water temp falls to 19.5°C, so a wetsuit becomes part of the kit. Precipitation is low at 2.37 mm/day. May is a very reliable month for quality sessions.
