Conditions at Avalon in October
October: Shoulder-Season Fun - E/SE Energy and Spring Sea Breezes
October marks a clear increase in easterly energy as the ocean transitions into spring/summer mode. The average wave period slips to 8.5s, but ideal wind conditions remain usable at 31%. Swell direction tables show a strong E/SE pulse: E 13%, ESE 12%, SE 16% and SSE 24%, with ENE 15% also feeding the beach. This is a good month for persistent E/SE groundswell, but the spring sea breeze is gathering strength, so afternoon onshores become more frequent. Average height stays at 1.3m (4.3ft), yet SSE pulses in the 1-2.5m (3-8ft) range are common enough to keep bigger-wave riders interested. Water temp is 18.9°C, air temp averages 18.0°C, and rain averages 2.06 mm/day. When a low-pressure trough over New South Wales produces pre-frontal NW winds, October can deliver surprisingly good, hollow Avalon sessions before the arvo onshore arrives.
