Conditions at Maroubra in December
December: Summer Energy, Choppy Afternoons
December is the beginning of the low season at Maroubra. Average swell dips to 1.5m (5ft) and the period stays short at 8.3s, while ideal winds sit at just 15 percent. The swell directional data is still busy, with SSE (18 percent), SE (15 percent), ENE (17 percent), E (14 percent) and ESE (13 percent), but much of this is short-period windswell and refracted NE/ESE swell. The wind regime is firmly summer: NE (16 percent), NNE (13 percent), S (12 percent) and SSE (11 percent), with the NE sea breeze arriving almost every afternoon. That makes the early morning hours precious. Water temp reaches 21.7°C, air averages 21.2°C, and precipitation is 2.43mm/day. On the bright side, tropical cyclones in the Coral Sea can still throw a long-period E/SE swell into the mix and make December a giant killer.
