Alright, grab a coffee, because I’m about to tell you something you probably don’t want to hear. The next two weeks at Mewslade Bay are a proper bust. Not one decent session in the whole 16-day run. That’s unusual for a spot that’s usually fairly consistent, but this stretch is dead. The water is way warmer than normal for this time of year—67°, which is about 8° above average—so that’s something, but it won’t help the waves.
We start Sunday July 5 with a tiny 1ft WSW swell and a cross-on wind—just messy and weak. Monday the 6th is similar, maybe 2ft but short period and still cross-on. Tuesday the 7th: clear skies, but the swell drops to 1ft and wind shifts cross. By Wednesday morning the 8th, it goes glassy with a 1.0ft W swell—no push. Thursday the 9th is dead calm, 1.0ft, period 10s, but nothing. Friday the 10th and Saturday the 11th finally see clean offshore winds (NE), but the swell is only 1–2ft. Too small to get excited about.
Then the second week kicks off with a bizarre stretch of tiny swell mixed with long periods—0.3ft with 16-21 second intervals on Sunday the 12th and Monday the 13th. That’s groundswell energy but basically no height. Tuesday the 14th has 1ft WSW with clean offshore winds and moderate energy (51), but still not surfable.
The only moment that even sniffs surfable is Saturday July 18 afternoon. Swell jumps to 4ft from WSW, period a short 6 seconds, combined energy 115—moderate. Winds are light and clean (cross-off). That’s the best of a bad lot, but it’s still only a 1 out of 10. After that, Sunday the 19th and Monday the 20th see bigger swell (4–6ft) but cross or onshore winds kill it.
So yeah, nothing worth paddling out for. Some kite surfers might eye the bigger days later in the second week when the wind is strong and cross, but for a surfboard, it’s a blank run. Forecasts can change, but right now it’s looking grim. Keep an eye on that July 18 window—it’s the only hint of something, but don’t hold your breath.
