Conditions at Blacks Beach in May
May: The Ocean Warms, But So Does the Wind
May is the doorway to summer, and for surfers at Blacks Beach that means a diminishing wave quality. The average swell height is still 1.1m (3.6ft), and the period is a long 13.5s, but the swell direction has rotated firmly into the southwest quadrant: WSW (39.5 percent), SW (30.3 percent) and SSW (7.8 percent) together dominate. These southern hemi swells are less efficient at this west-facing break, often arriving as soft, irregular lines. Wind is the real limiting factor. Ideal offshore flow plummets to just 8 percent, with onshore W (25.9 percent) and WSW (25.0 percent) blowing directly into the beach nearly every afternoon. Water temps climb to 16.2°C (61°F), air temps average 16.5°C (62°F), and rain is scarce at 0.26 mm/day. For the dedicated, early morning high-tide sessions can still produce fun, rippable waves before the seabreeze turns things messy.
