January: Mid-Summer Trade-Wind Grind
January is classic mid-summer surf on the Sunshine Coast: hot, humid and dominated by the E-SE trade winds. Swell data shows a strong E influence at 36%, with another 23% from ESE and 11% from SE, most of it in the 3-5ft (0.9-1.5m) range and an average period of 8.0s. That combination keeps the banks bowling and punchy, but the wind is the limiting factor. ESE (15.5%), SE (19.3%) and SSE (10.2%) all blow straight onshore, leaving only 15% of the time with ideal west-to-northwest winds. Occasional tropical cyclones or monsoon troughs can deliver larger E-ENE swell in the 6-8ft (1.8-2.4m) range, but usually with messy, onshore conditions. Air temperatures average 25.0°C and water temperatures hit 26.0°C, so it is very much a boardshorts-and-sunscreen surf.
