Conditions at Nalvo in May
May: Habagat Clouds Are Gathering
May is the doorstep to the southwest monsoon. The average swell remains small at around 1.5-2ft (0.5m), but the direction signature starts to change: WSW (20.9%) and SW (12.9%) become the leading swell sources, with a healthy NNW (18.9%) leftover from the old monsoon pattern. Periods are short at 5.7s, and ideal surf winds hit their annual low of 15 percent. The wind rose turns toward S (10.1%), SSW (10.5%) and SW (8.8%), bringing humid, bumpy conditions. Rain climbs to 6.63mm/day, air temp averages 27.4°C and water is a balmy 30.0°C. Surf quality is poor overall; only a lucky morning with E/SE offshore and a building WSW swell can offer anything worth a paddle.
