January: Summer Consistency, Average Conditions
January sits in the heart of the summer doldrums for Motunau. Average swell height is 3-4ft (1.1m) with a period of 9.5s, which keeps the surf in the small, fun-sized range. Energy is dominated by easterly quadrant swells - ENE and E alone account for 39 percent of readings, with ESE adding another 14 percent. The desirable S and SSW directions make up only around 9 percent, so true quality days are a bonus rather than the norm. Winds are ideal only 33 percent of the time; the morning NW offshore can groom the waves, but the NE/ENE sea breeze often kicks up by midday, creating average, punchy conditions. With air temperatures near 16.4°C and water at 16.7°C, a 3/2 wetsuit is comfortable and the lineup is best in the early hours.
