Conditions at Lennox Head in December
December: Summer Easterlies and Holy Grail Windows
December is a month of high potential but low hit rate. Average swell stays at 1.5m (5ft), the period is a short 8.3s and ideal wind is only 31%. The swell direction is heavily tilted toward the good zone-ENE (14.3%), E (17.5%), ESE (17.2%) and SE (15.6%)-and the average conditions produce plenty of 1-2m surf. The problem is the NE/NNE/SE trade wind regime: NNE (13.0%), NNW (14.3%), NE (8.6%), SE (8.4%) and SSE (9.7%) keep the surface bumpy through the day. Water temp warms to 23.5°C, air to 23.8°C and rainfall is 4.21 mm/day. Look for early-morning glass, southerly changes, or tropical cyclone swell events to unlock the classic Lennox perfection in December.
