Conditions at Cat Bay in January
January: Mid-Summer Clean Machine
January is peak summer and Cat Bay is as consistent as it gets. The average swell height is 1.4m (4.6ft) at a solid 11.2s period, and 45% of all wind observations are ideal. Swell data shows a heavy dominance from the southwest quadrant, with SW accounting for 54.9%, SSW for 19.9% and WSW another 6.0%. Direct N/NW swell is practically absent, so most waves are refracted SW groundswell. Wave heights cluster in the fun-sized 3-5ft (0.9-1.5m) range, with SW alone holding about 14% of the total swell in the 5-6.5ft (1.5-2m) class. Wind conditions are friendly: SSW, SW and S winds combine for roughly 35% of observations, while onshore N/NNW winds stay below 8%. With water temperature at 18.5°C and air temperatures averaging 18.1°C, January offers warm, clean, rippable surf.
