Conditions at Whale Beach in December
December: Summer Solstice and the Daily Onshore Gamble
December is a month of short-period east swell and persistent onshore winds at Whale Beach. Ideal wind is only 21%, with NE 11.7%, ENE 13.0%, E 8.0%, ESE 6.3%, SSE 10.2% and S 9.5% dominating the wind rose. The swell direction remains excellent in theory: ENE 19.1%, E 17.5%, ESE 16.4%, SE 17.8%, SSE 19.5% and S 4.6%, keeping the average height around 1.3m (4.3ft). But the average period falls to 8.1s, meaning the waves lack the power and structure of a proper groundswell. The significant ENE/E swell generated in the Coral Sea and western Tasman generally shows up as lumpy, wind-affected surf when the afternoon seabreeze is up. Water temp is 21.1°C, air temp averages 21.6°C and precipitation is 2.7mm/day. Early morning with a W/NW offshore wind is the golden window; otherwise, it is a tough battle against onshore texture.
