Conditions at Sri Lanka in March
March: Transition Begins, Still Lots of Ins
March sees the first signs of the monsoon flip, yet plenty of windows remain. The westerly wind flow is still strong - 20.9% out of the west, 10.0% from the west-northwest and 9.1% from the west-southwest - but the east to southeast wind component is building (E 9.5%, ESE 11.4%, SE 7.0%), so the afternoons get increasingly cross-onshore. The wave rose is still dominated by SSW-directed energy at 58.8%, with an additional 30.8% aimed at the southwest; that keeps the swell source firmly in the NE quadrant. Average heights ease slightly to 5.2ft (1.6m), but the average period bumps to 13.3s, meaning long-period, powerful lines. Ideal wind drops to 48%, so mornings and evening wind-shadow spots will be the go-to. Water temp is 29.1°C, air temp 27.9°C, and precipitation drops to 5.83 mm/day - a sign the wet season is easing.
