The Lowdown
Alright, Rusty here again. Let’s talk about what’s happening at Topaz Street over the next couple of weeks. This is a beach and jetty spot, open to west swell, and it’s mostly a beginner-friendly wave. Crowds are possible now and then.
Water temperature is about normal for this time of year, nothing unusual.
It’s a slow start. The first few days have tiny swell and rough conditions. Friday the 11th is a total washout with onshore winds. Saturday the 12th morning is the best of the early bunch – a clean 2ft south-southwest swell with a nice 14-second period and light cross-offshore wind. Combined energy is moderate at 200. It’s rideable but nothing special. Saturday afternoon turns onshore and gets messy.
Sunday the 13th through Tuesday the 15th are poor – small, weak swell with mostly cross-on or onshore breezes. Energy sits in the low to mid 100s. Not worth the hassle.
Wednesday the 16th morning is a decent little window. Clean conditions with a 2ft south-southwest swell, a long 17-second period, and light cross-offshore wind. Combined energy is moderate at 232. The waves will have some push and shape, but it’s still small.
The standout is Sunday the 20th morning. That’s the one. A 2ft southwest swell with an 18-second period – real groundswell that’ll bend into the jetty nicely. Light cross-offshore winds from the southeast will keep it glassy. Combined energy jumps to a strong 403. It’s clean, the sets will have some punch for the size, and it’s the best session in the whole run. Afternoons get blown out by west wind, so get there early.
Monday the 21st morning still has some energy at 417, but the wind is cross-shore and clouds are around. It’s okay but not as clean. From Tuesday the 22nd onward it’s all onshore west wind and small, junky swell – nothing to get excited about.
Bottom line: Sunday the 20th morning is your best bet. Clean, solid energy, and that long-period southwest swell will give you some proper little waves. Topaz Street won’t be firing, but for this two-week stretch, that’s the day.
Rusty.
