December: Peak Season at Jaws
December is the pinnacle of the Peahi calendar. Average swell height reaches 6-7ft (2.0m)-the highest of any month-and the period sits at a thumping 12.3s. NNW swell leads the charge at 23.9%, with N and NW adding another 11.4%, so over a third of all swell energy is coming from the optimal north and north-northwest window. Pulses in the 5-8ft (1.5-2.5m) range are common, and occasional XXL waves push past 8ft (2.5m). Trades still blow hard from E and ESE about 65% of the time, but ideal offshore wind is 22%, meaning the cleanest Jaws sessions often happen in December. Air temp averages 23.0°C, water temp 24.7°C, and rainfall is high at 1.84mm/day. The North Pacific has delivered the goods.
