Conditions at Mona Lisa Point in May

May: First Taste of the Habagat

The southwest monsoon begins to stir in May, and Mona Lisa Point starts to pay the price. The swell direction actually rotates into the productive west quadrant - WSW jumps to 20 per cent, W to 14 per cent, and WNW to 9 per cent - but the wind follows the same path, with S/SSW/SW flow combining for about 40 per cent of all observations. That is a classic onshore setup for a west-facing beach, and the ideal-wind number plummets to just 3 per cent. Wave heights bottom out at 1ft (0.3m) with a 5.5s period, so any swell is both tiny and short-period. Air temperature reaches 29.2°C (84.6°F), water temperature is already 30.2°C (86.4°F), and rainfall rises sharply to 7.89mm/day. The only windows come when a passing trough brings early-morning land breezes before the afternoon seabreeze ruins it.
