The Lowdown
Alright mate, let’s break down what New Brighton Beach has in store for the next couple of weeks.
The only real standout is on Saturday the 18th of July. We’ve got a solid 4ft swell coming out of the SSE with a super long period of 23 seconds – that’s proper groundswell with plenty of grunt. The combined energy is cranked right up at 2279, so there’s definitely power behind it. Glassy conditions with a light NNE breeze at just 3 mph mean the surface will be butter smooth. Water temp is 50°F, which is about what you’d expect for this time of year. This is prime for experienced surfers, but that long period can make beach breaks a bit shut-down. Crowds are a possibility, so be ready for company.
Sunday the 19th drops off to a small 2ft easterly swell with a 13-second period and a clean offshore wind from the SW at 9 mph in the morning. It’s surfable but nothing to write home about. The afternoon goes glassy but even smaller.
Monday the 20th has similar small 2ft SSE swells with a long 19-second period and moderate energy (374). Glassy offshore wind in the morning keeps it clean, but the size is lacking.
From Tuesday the 21st right through the end of July, it’s mostly tiny, weak, and disappointing. We get a few glassy mornings with waves barely reaching 1ft to 2ft, and energy readings mostly below 200. Not worth suiting up for. The 23rd has a brief 3ft NE swell, but with a pathetic 5-second period, it’ll be lumpy and weak.
The end of July and beginning of August is more of the same: tiny swells, strong onshore winds, and choppy, messy conditions. The 28th has a 4ft NE swell in the afternoon, but with a gusty onshore breeze at 9 mph and short period, it’ll be blown out and ugly.
Bottom line: Saturday the 18th of July is your only real window. After that, it’s a long, flat stretch with just a few clean but tiny mornings. For this area, that kind of dry spell isn’t unusual. Forecasts can shift, but for now, don’t expect much.
