June: Peak South Swell Under a Rainy Sky
The Southern Hemisphere winter drive is in full swing by June, pushing the average swell height to 1.4m with a 13.7s period. The SSW and SW directions supply over 98% of the wave energy, and 21% of the surf reaches 5-6.5ft (1.5-2m), so there is no shortage of raw power. But the wet season is now overhead: ideal wind falls to 23%, and onshore/cross-onshore flow from the S, SSW, SW and WSW makes surface conditions messy and lumpy. The wind rose is widely spread, with WSW, W, WNW and NW all becoming more frequent - none of which offer the clean, offshore groom that Jaco needs. Rain averages 7.80 mm/day, air temperatures sit near 26°C (23-32°C), and water temperature is 29.0°C. June is for the dedicated charger who can tolerate less-than-perfect texture.
