October: Spring Size Meets Southern Swells
October delivers a dramatic spike in SSW energy, with SSW alone accounting for over 23% of all wave energy and SW adding another 13%. Average wave height remains around 6ft (1.9m) with a 10.9s period, so there is plenty of power - just from the wrong direction. The NE/ENE share is still enough to keep Aramoana interesting, but only when the synoptic setup allows those swells to wrap in cleanly. Ideal offshore wind time is 24%, with WSW and SW breezes offering the best surface conditions after cold fronts pass. Air temps average 9.9°C, water temp is 10.9°C, and rain increases a bit to 1.92 mm/day. Spring is all about timing: hit the windows between fronts when the NE quadrant gets a look in.
