The Lowdown
Alright, Rusty here again. Let’s break this down in the old units.
We start off slow on Saturday, the 25th of July. Morning is a mess—wind is cross-on, swell is 10ft, and the energy is massive at 4907, but it’s ugly. Don’t bother. But Saturday afternoon, it all cleans up. The wind goes glassy, swell jumps to 13ft from the west, and the energy is a huge 6600. That’s a heavy, powerful groundswell, but at 13ft, it’s for experts only. Beginners, stay on the beach. The wave period is 14 seconds, so long lulls but serious power when the sets come. Cobden Breakwater is gonna be the big standout for the crew with the skills.
Sunday the 26th is still solid—7ft from the west, 14 seconds—and the morning is clean with a cross-off wind. Energy is 1887, so it’s got some muscle, but it’s not the monster Saturday was. If you couldn’t get out Saturday afternoon, Sunday morning is your next best window.
Through the week, it settles. Monday the 27th and Tuesday the 28th have smaller swell—6ft dropping to 3ft—with clean conditions and glassy moments. The energy drops into the low hundreds. Still fun, but not the big stuff.
End of July and into early August, the swell fires back up. Thursday the 30th morning: 6ft from the west-northwest, 13 seconds, offshore wind. Clean and solid. Friday the 31st afternoon: 10ft from the west, 12 seconds, offshores—energy at 2681. Big, powerful, and clean. Pros only.
The second week, Monday the 3rd of August and Tuesday the 4th of August both have 6ft to 7ft swells from the west-southwest, with long periods from 15 to 18 seconds, and glassy or clean cross-off winds. Energy is 2120 and 1709. These are excellent, powerful groundswells—the best of the second week. After that, the swell fades to 1ft or less by the 6th through the 9th, with energy under 100. Not much doin’.
Water temp at Cobden Breakwater is 54°, which is just about normal for this time of year. Crowds are rare, so you’ll have the place mostly to yourself.
Rusty out.
