Conditions at Tago River in December
December: Big NE Monsoon Swell, Dirty Wind
December closes the year with the most consistent heavy swell of the season. Average height climbs to 6ft (1.9m), period is a solid 10.1s, and the swell window is textbook: NE (60%), ENE (16%) and NNE (11%) add up to about 88% of the wave energy. The size is legitimately pumping - nearly half the readings are in the 5-6.5ft (1.5-2m) range and another 23% are 6.5-8ft (2-2.5m). The catch is the NE monsoon wind: onshore N/NNE/NE/ENE flow returns to around 50%, while ideal S/SSW/SW/WSW wind sits at only 5% and the ideal-wind frequency is 13%. Big but bumpy is the norm; save your energy for the rare offshore day when these 10s groundswells are groomed into epic, firing waves.
Air temps cool slightly to 26.1°C (21.7-30.8°C), precipitation is 13.91 mm/day, and water temp is 28.5°C.
