Conditions at Yumuri in January

January: Peak Winter, High Hopes

The heart of winter brings the largest average surf of the year to Yumuri, with wave heights around 3.5ft (1.1m) and periods averaging a rideable but short 6.3s. ENE swell dominates an incredible 67% of the time, with NE swell adding another 16%, meaning most of the energy is arriving on an oblique angle for this north-facing beach. What January lacks in perfect direction, it makes up for in size and occasional consistency: the 5-6.5ft (1.5-2m) range shows a healthy 12% of the total, and the biggest winter swells can push into 6.5-8ft (2-2.5m) territory. The wind patterns are far from user-friendly, however. ENE winds blow 38% of the month, frequently at 20-40kph, and NE winds add another 18%, creating bumpy, cross-shore chop. Only 7% of the time does the wind shift offshore out of the S/SW. When that offshore window meets a North Atlantic low-pressure system with a negative NAO signature, Yumuri can light up with clean, powerful N/NNW groundswell. Water temperature sits at 26.2°C, air temps average 24.9°C, and precipitation is moderate at 1.21mm/day.
