Conditions at Supertubes in January
January: High-Pressure Summer Lull
The Southern Ocean is still active enough to send a 6ft (1.9m) average southwest groundswell, with SSW and SW directions combining for over 70 percent of the wave rose. However, the average period of 11.8s stays on the shorter side of the long-period window, which keeps Supertubes from reaching its classic heavy, dredging potential. There is no meaningful N/WNW/NW swell in the data, so the reef relies almost entirely on Southern Ocean pulses sneaking into the northwest-facing bight.
Winds are the bigger issue. The summer high-pressure belt and afternoon sea-breeze cycle produce a strong SSE-SE signature, with SSE at 23.1 percent and S at 20.4 percent. Offshore flow from the S/SSW/SW/WSW quadrant is present in the wind rose, but only 17 percent of the time is it clean and light enough for perfect conditions. With air temperatures around 20.4°C (13.3-31.8°C), water temperature at 20.6°C and only 0.42 mm/day of rain, expect warm, dry, often bumpy summer surf.
