Conditions at Castaways in October
October: The Calm Before the Onshore Storm? Not Quite
October is the transition from southwest to northeast monsoon, but it still leans heavily towards onshore conditions. The swell average is 1.5m (5ft) with a slightly shorter 10.5s period, and the direction is still excellent - S (32%), SSE (24%), and SSW (18%). Winds, however, are still dominated by WSW (22.5%) and W (23.7%), meaning ideal wind is only 20% of the time. That said, October is a month of increasing variability. As the month progresses, NW winds become more frequent, and the first proper offshore windows of the build-up season appear. If you time a late-October trip right, you can catch the first taste of the dry season.
