Conditions at Newport in May
May: Westerly Grooming Meets Winter Swell
May is prime time. Favourable winds jump to 41%, average swell period reaches 9.5s, and average height stays at 4-5ft (1.2-1.5m). The swell mix shifts south, with SSE (24%), SE (18%), S (13%) and ESE (14%) doing most of the work. That is a little less ideal on the compass than the pure summer east swells, but the wind is the great equalizer: WSW-WNW offshore flow totals about 34% of all wind observations, cleaning up every swell pulse. Air temperatures drop to 15.3°C, water temperature is 20.8°C, and rainfall is modest at 2.04 mm/day. Expect crisp mornings, groomed faces, and long-period lines that make Newport feel more like a proper point-break setup than a summer windswell beach.
