Conditions at Pikinini in September
September: Glassy Mornings and a Touch More Period
September is arguably the most reliable month for clean conditions. Ideal wind sits at 66%, with ESE (26%), E (19.3%), and SE (18.5%) winds blowing offshore almost daily. Rain drops to the year's minimum at about 5.5 mm/day, and water temp remains warm at 29.3C. While the average swell height is still only 2-3ft (0.8m), the period lifts back to 8.9s, adding a little more push to the ENE (34.6%) and NE (24.7%) trade swell. This is a great shoulder-season month: the ocean is beginning to regain some period, and the offshore winds are consistent enough to make every pulse count. Direct NE swell remains shadowed on the west-facing reefs, but northwest and west-northwest energy becomes slightly more noticeable, so keep an eye on the longer-period models.
