Conditions at Scar Reef in January

January: The Northwest Monsoon Slams the Door

January is deep in the north-west monsoon, and the numbers are not pretty for Scar Reef. Ideal wind sits at just 29 percent, with the bulk of the wind coming from NNE (15.3%), WSW (13.9%), SW (12.8%) and W (9.1%). Most of that blows cross-shore or onshore onto this north-west-facing reef, so the wave faces are frequently bumpy and hard to read. Swell averages 4ft (1.3m) at 12.6 seconds - still technically long period - but it arrives almost entirely from the SSW (42.4%) and SW (56.0%), not from the N/W/NW directions this set-up prefers. With high rainfall pushing 7.94mm/day, warm air at 26.6°C and water temperature 29.5°C, expect humid, scattered showers and only small windows of clean SSE to S offshore flow. On those rare days the reef can still produce fun, rippable waves, but consistency is a serious issue.
