Conditions at Isdhoo in January
January: Northeast Monsoon Slop
January is the heart of the northeast monsoon, and for a north-facing reef like Isdhoo it is a frustrating month. The wind rose is dominated by NE (35%), ENE (20%) and NNE (19%) directions, with much of the flow blowing 10-30kph - onshore and textured. Ideal wind for surfing is only 5%. Average swell is 3-4ft (1.1m) with a short 6.4s period, so expect average, punchy but windswell-like waves. The wave rose is dominated by ENE (40%) and E (28%) swells, with smaller contributions from ESE (11%) and NE (8%). This means the swell is coming from east/northeast - close to the optimal N/NE window - but the onshore NE wind usually makes a mess of it. Water temp is a warm 28.5°C and air 27.3°C, but precipitation is moderate at 3.1mm/day. This is a month for low expectations and picking the brief windows between trade-wind pulses.
