Conditions at Mabuntok in May
May: Clean but Grovelly
May is the month when the Southwest Monsoon (Habagat) starts to take over, and the shift is dramatic for wind quality. The ideal offshore wind percentage jumps to 38 percent, with S/SSW/SW/WSW directions showing up regularly alongside the E/ESE trades. The trade-off is size. Average swell height drops to 2ft (0.7m) and the period shortens to 8.9s. ENE remains the primary swell direction at 62.7 percent, but E is up to 27.4 percent and there is almost no NE energy left. The E/ENE swell is more local windswell than true groundswell, so it tends to be crumbly and sectiony, although the clean offshore winds help it hold shape far better than in winter. Expect longboard and fish conditions: 2ft (0.6m) corners and the occasional waist-high set. Air temperatures warm to 28.0°C, water temperature hits 29.2°C and rainfall drops to 5.5 mm/day, making it one of the driest and most pleasant months to be in the water.
