Conditions at Cape Town in January
January: The Cape Doctor Takes Over
January is peak summer at the Cape, with the South Atlantic high locking in strong southeasterly flow. The wind rose shows SSE winds at 35.4%, SE at 15.8% and due S at 18.0%, so this NW-facing beach sees plenty of offshore eastern-southerly conditions. The catch is wind speed: once the Doctor kicks into the 20-40kph range, the surface becomes bumpy, which is why only 28% of the time winds are truly ideal. Swell averages 7-8ft (2.1-2.4m) with a long 11.1s period, and the dominant direction is SW (27.6%) with strong SSW (17.8%) and S (10.6%) contributions. There is almost no pure N/NW groundswell, so those S/SW pulses wrap into the bay. Air temperatures reach 20.0°C, rain is minimal at 0.39mm/day, and water temperature sits at 14.8°C. Expect clean dawn sessions, fun rippable surf, and afternoon corduroy blown out by the seabreeze.
