October: Building Summer Swell, Fading Offshore Flow
October is a true transition month at Dee Why Point. The average swell height stays at 5ft (1.6m) and the average period drops slightly to 8.7s as the winter groundswell machine begins to wind down. The good news is that the optimum NE, ENE, E and ESE swell directions make up around 40% of the total energy, fueled by a reawakening Tasman Sea and early subtropical systems. The bad news is that the ideal wind percentage drops to 26%, with NE and ENE winds becoming more frequent as the summer pressure pattern strengthens.
Water warms to 19.2°C while air temperatures average 18.1°C, and rain totals climb slowly to 2.04 mm/day. October favors the flexible surfer: chase the more easterly swell, surf the morning tide, and get out before the seabreeze chops it up.
