The Lowdown
Rusty again, let’s talk feet and miles per hour.
We’re on Spanish Bay-South Moss. Advanced wave, pretty consistent but fully exposed, and they like it from the west.
To start with, through late July we have chest-high, waist-high swell running in from the west-northwest at 16 to 17 seconds, wave energy is moderate. Problem is the wind – it is blowing onshore at 12 mph from the northwest or west-northwest. Water temp is 59°F, about right for summer. Poor conditions on Friday the 17th and Saturday the 18th. Not worth suiting up.
Sunday the 19th is still only marginal. Swell sits at 3 ft to 3 ft from the SSW to SW, long period, but the wind stays cross-onshore. Light wind on Tuesday morning (21 July). That is a standout for the first half. Swell at 4 ft from the SSW, period 14 seconds, wave energy moderate (727), and wind at 3 mph from the west-southwest, just a light cross-shore. That morning window is the cleanest you will find. Crowds? Sometimes. Water temp is normal.
From Wednesday 22 through Friday 24 July, it gets poor again. Small swell, wind cranking, not much to say. There is a 24-second groundswell on Friday the 24th – combined energy 845 – but it is blown out. Saturday the 25th and Sunday the 26th have bigger energy, 1377 and 1161 (strong), but still onshore wind at 12 mph.
Monday 27 July through Wednesday 29 July stays in marginal range but swell builds to 4 ft to 5 ft. The afternoon of the 27th shows combined energy at 1686 (very strong), but again, wind is on. By Thursday 30 July the swell jumps to 6 ft from the northwest, period 9 seconds, wind light cross-onshore at 6 mph. Combined energy 1154 (strong). That is the standout for the second half. Friday 31 July and Saturday 1 August hold similar: 7 ft to 8 ft from the north-west to west-northwest, period 10 seconds, combined energy over 1100, with light cross to cross-onshore winds. That looks heavy for advanced surfers. Beginners – stay on the beach. Too big.
The short period means it might be a bit lumpy, but the light wind will help. On the other hand, with these cross-offshore and cross winds on an exposed beach set-up, the kite crew might be really into it.
Rusty out.
