Conditions at Aramoana in January
January: High Summer's NE Window
January delivers Aramoana's most consistent taste of N through ENE swell, with the ENE component accounting for nearly 12% of all wave energy and NE adding another solid slice. The average swell height sits at 5-6ft (1.7m) and periods average 10.2s, putting most surf in that powerful, long-period category. The main issue is surface texture: NNE and NE breezes dominate at more than 30% combined, exactly the onshore direction that wrecks wave quality. Yet when a south-west change sweeps the coast - and ideal offshore winds blow around 22% of the time - those ENE pulses groom into clean, rippable lines. Water temp is 14.1°C, air temps average 13.8°C, and precipitation averages 2.24 mm/day. Dawn and dusk sessions in a 3/2 steamer are the play during the Southern Hemisphere summer.
