June: Peak South Swell Season, but the Onshore Wind Wins
June cements the summer south-swell pattern. The average swell is 0.7m (2.3ft) and period 7.8s, with S (33.6%), SSW (24.3%) and SSE (20.5%) energy combining for over 78% of all waves - a perfect directional match for the beach's south-facing orientation. If the wind were favourable, this month would be an absolute standout. But it isn't: SSW (16.6%), S (14.3%), SW (10.6%) and SSE (6.9%) make up nearly half the wind distribution, while offshore N/NNE/NE/NNW flow drops to about 30%. The 16% ideal wind figure says it all - most days are bumpy, soft and onshore. Water temperature rises to 21.5°C, air temps to 20.7°C, and precipitation jumps to 6.01 mm/day as the seasonal rains add moisture. Surfers can still find rideable waves on south pulses, but expect a constant battle with the afternoon seabreeze and lumpy conditions.
