Conditions at Virac Harbour in May
May: The Habagat Starts to Spoil It
May is when the southwest monsoon begins to influence the Philippines, and Virac Harbour feels it immediately. Average swell drops to 0.6m (2ft), period 7.6s, and ideal wind plunges to 7%. The swell rose is still dominated by E (49.6%) and ENE (33.9%), but S, SSE, and SE components start to appear, offering a hint of the summer pattern to come--though almost all of it remains below 1m (3ft).
Wind becomes a messy mix: E 21.6%, ESE 20.5%, ENE 12.7%, SE 11.7%, with SSW and SW already combining for over 12%. The southwesterly winds are directly onshore at this southeast-facing spot, so wave quality suffers even when there is some energy. Rain is still moderate at 5.20 mm/day, air temps average 28.2C, and water temperature reaches 29.5C. May is a month of morning calm and afternoon chop, with little real surf on offer.
