Conditions at Zavial in October
October: The North Atlantic Roars Back
October is when Zavial turns from a summer beach back into a real surf break. The average swell height climbs to 5-6ft (1.5-1.8m), the period extends to 11.4 seconds, and ideal wind sits at 42%. The Atlantic low-pressure train starts firing up, bringing a sharper S/SW component (about 1.5%) while still riding on a base of NW (38.0%) and WNW (17.7%) groundswell. The wind rose shows more N/NNE and NNW flow, which is textbook offshore for the SSW-facing beach, and fewer strong summer north-westerlies. Water holds at 19.2°C, air highs still reach 28.7°C, and rainfall climbs to 2.23mm/day. The season of heaving, long-period swell has officially begun - pick the S/SW days and thank the low pressure.
