The Lowdown
Imperial Units
Alright folks, Rusty here. Let’s break down what’s coming for the local spot. The first week is a bit of a slow burn, but there’s a chance for something a bit meatier if you can wait.
So, we’re looking at Trestles (Uppers). It’s a reef and point, pretty consistent, and it’s exposed to the swell. The water is 71° right now, which is much warmer than usual for this time of year – about 4° above the average, so you’ll be comfortable in a shorty or springsuit.
From Saturday the 18th through to Thursday the 30th, the swell is really small. We’re looking at waves mostly 2ft to 3ft from the SW or SSW. The energy is all low to moderate (364 to 771 combined energy), and the period is a solid 13 to 18 seconds, so it’s a proper groundswell, but there’s just no size. The wind is the real killer here. It’s almost always onshore or cross-onshore from the SW or WSW. It’s light, but it’s blowing right into the face of the wave. The surf will be weak and the shape will be poor. The conditions are marginal, and honestly, it’s not worth getting too excited about. The morning of Saturday the 25th has a little pulse of energy (1056 combined energy) with a 3ft SSW swell and a very long 21-second period, with a light offshore wind. That’s your best bet in the first week, but it’s still tiny.
Now, let’s talk about the end of the month. On Friday the 31st of July, the swell finally shows up. We’re looking at 8ft from the S, with a strong 14-second period. The energy is over 2000 (2181 combined energy), which is strong. That’s a proper wave. The wind on Friday morning is light offshore, which is perfect, but it goes cross-onshore in the afternoon. That swell hangs around into Saturday the 1st of August, with 6ft to 6ft from the S, but the wind stays cross-onshore from the W. At 8ft, this is a wave for experienced surfers only. The standouts are the morning of Friday the 31st of July, and maybe the morning of Saturday the 1st of August, but the wind is a factor on the Saturday. This is a long-range call, so it’s not locked in, but it’s the only real size we’ve got in the whole 16-day window. After that, it fades back to tiny 4ft slop on Sunday the 2nd of August.
If you’re into kite surfing, the wind is mostly too light to bother, and the break is a reef and point, so paddling is the name of the game.
Rusty.
