Conditions at Yumuri in December
December: Winter Swells Peak
December delivers the peak winter size, with average surf reaching 3.5ft (1.1m) and periods around 6.3s. The ENE quadrant is back to a commanding 72%, and notably, the 5-6.5ft (1.5-2m) class accounts for nearly 15% of the month, with another 4% in the 6.5-8ft (2-2.5m) range. This is the most consistent winter surf of the year, but it comes with a trade-off: ENE winds blow 43% of the time, including a strong 30-40kph signal, and ideal offshore winds are at their yearly low of just 5%. That makes December a month of raw power more than clean perfection. The real gems arrive when a strong North Atlantic low and a negative NAO combine to produce true NW/NNW groundswell; on those rare days, Yumuri turns into an entirely different, much more serious wave. Water temperature eases to 26.8°C, air temps average 25.6°C, and rainfall is fairly low at 1.39mm/day.
