October: Autumn Swell Machine Engages
October is when El Mongol starts to roar again. Average wave height jumps to 4-5ft (1.4m) with 11.2s periods, and the NW direction reaches nearly 48% of all observations. NNW and WNW add another 34%, giving the exposed north-facing beach a strong Atlantic fetch. Ideal S/SSW/SW winds blow about 48% of the time, and the wind rose also features ENE, E, S and W, so the favourable days are usually tied to a building pressure gradient behind an approaching front. Cooler autumn air often brings glassy mornings before the sea breeze shows up. Water temperature is still pleasant at 17.2°C, air temps average 15.6°C, and rainfall picks up to 2.98mm/day. This is a proper pre-winter ramp, with sandbanks starting to show real shape again.
