Conditions at Castaways in January
January: The Monsoon Gold Standard
The northeast monsoon locks in for January, offering the most reliable surf windows of the year. A strong semi-permanent high over the Indian subcontinent drives steady offshore flow - predominantly NNE and NNW - and with ideal wind conditions 67% of the time, the surface at Castaways is often clean and lined up. The average swell height is a user-friendly 1.2m (4ft) with a 10.1s period, and the direction is heavily loaded in the SE (21%), SSE (15%), and S (11%) sectors, with a further push from ESE and SSW. Put simply, the south-facing beach is being fed appropriately long-period groundswell that is both powerful and rippable. Water temps of 28.8°C and tropical air averaging 27.3°C keep everything pleasant, while moderate rainfall (4 mm/day) rarely persists for long.
