Conditions at Millers in December
December: Summer Magic Begins
December closes the year with the best overall combination of size, period and clean wind. Average swell is 6.6ft (2.0m) at 10.7s - punchy and playful rather than extreme. The SSW sector roars back to 29.1 per cent, with SW at 18.1 per cent and S at 14.6 per cent. The biggest chunk of waves sits in the 5-8ft (1.5-2.5m) range, ideal for a north-east-facing wave that needs south swell to wrap in. The ideal offshore wind frequency returns to 29 per cent, with SSW at 6.7 per cent, SW at 12.6 per cent and S/SSE at 9.6 per cent. The E/ENE flow (25.8 per cent) is cross-offshore and often makes morning glass. Water temperature warms to 19.6°C, air averages 20.8°C, and rain is 1.24 mm/day. December is the start of the golden window - long, clean, glassy sessions are the norm rather than the exception.
