Conditions at Cotton Trees in January
January: The Grovel Season
January is a small-swell month at Cotton Trees. Average heights sit at 3ft (0.9m) with a 10.7s period, and the swell board is dominated by due south energy: S accounts for 63.7% of all readings, nearly all in the 2-3ft (0.5-1m) range, while SSW contributes another 35.1%, including some 3-5ft (1-1.5m) sets. True SW or W swell is virtually absent, so the west-facing beach relies on angled southerly groundswell to reach the coast. The wind is the bigger issue: SW and WSW winds combine for roughly 42% of the month, blowing straight onshore, and the ideal NE-through-ESE offshore flow is rare. With 14% ideal conditions, 28.1°C water and only 0.35mm/day of rain, you are hunting for clean early-morning windows rather than a full day of surf. Air temperatures sit near 26.9°C.
