Conditions at Monobegawakakou in May
May: Warmth Arrives, But the Ocean Stalls
May sees the first real loss of winter consistency. The average period drops to 7.7s - the shortest of the year so far - and wave heights ease back to 2.6ft (0.8m). Swell direction is dominated by SE (34.4%) and SSE (26.5%), with S at 16.0%, but most of that energy is soft 1-3ft (0.3-1m) windswell. The wind roses start to look bipolar: NNW/NNE and NE still deliver offshore flow around 41% of the time, yet the SSW/S/SW sector now combines for 24.1%, bringing frequent sea breeze and onshore afternoon sideshore conditions. Air temperatures climb to 18.3°C and water to 20.5°C, making the occasional clean morning very appealing, but the lack of long-period energy keeps quality average. A passing typhoon far to the south is the only way to produce real May juice - otherwise plan for small, rippable summer-approach surf.
