Conditions at Backdoor in June
June: Lightweight Trade-Wind Chop
June is where the North Pacific surf engine essentially idles. Average swell height is 1.7m (5.6ft) and period drops to 8.2s. The swell rose is almost entirely ENE (54.7%) and E (28.0%), with NE at 10.1%; there is virtually no NNW or NW swell energy. These are locally generated, short-period windswell lines, not the organized ground swell that Backdoor needs. The wind situation is just as lopsided: ENE (48.1%) and E (44.9%) combine for 93% of observations, leaving only 13% ideal offshore wind. Expect mostly small, bumpy, sectiony waves, with occasional groveling conditions on the more exposed parts of the reef. Air temperature averages 25.2°C (min 21.9°C, max 29.5°C), precipitation is low at 0.96 mm/day, and water temperature is 25.6°C.
