The Lowdown
Alright, let’s talk in feet and miles per hour now.
Water temp at Playa de Somo is about normal for mid-September, nothing wild.
We start slow. Thursday morning the 17th of September has a marginal 5ft NW swell with an 11-second period, but a cross-onshore wind kills it. Friday the 18th stays messy with onshore winds. Hang in there.
Then the good stuff arrives. Saturday morning the 19th of September is the real standout: clean conditions, light cross-offshore breeze from the ENE at 3 mph. Swell is a solid 7ft from the NNW at 13 seconds. The combined energy of all swells is 1465 – that’s moderate to strong punch. Faces will be clean, lined up, and powerful. This is expert territory being over 8ft – not for beginners, but for the rest of you, it’s prime.
Sunday morning the 20th is another clean one: cross-offshore wind, 6ft NNW swell, 11 seconds. Fun and clean, slightly smaller. Monday the 21st keeps it going at 5ft with a longer 12-second period.
Things drop off after that. Tuesday the 22nd morning goes glassy but only 4ft – worth a quick session. Wednesday the 23rd morning has a long-period 15-second groundswell at only 3ft – that long period can make a beach break tricky, closing out sections.
From Thursday the 24th onward, it’s a long stretch of poor conditions: onshore wind, tiny surf, choppy water. A few glassy mornings like the 26th and 27th but with very small, hard-to-catch waves.
No real recommendations from the 24th of September through to the 1st of October. It’s a quiet spell.
Bottom line: Saturday the 19th morning is your absolute best bet. Clean, solid, and a good amount of power.
Rusty.
