The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking.
Honestly, we’ve got a bit of a flat spell to kick things off. The first real chance to get wet doesn’t look promising until late in the run, and even then it’s a bit of a stretch. For the first week plus, it’s a whole lot of small, messy, or just “poor” surf. The energy is low, and the conditions are fighting us. The standout, the only break with any real potential in the whole 16-day window, is Tennis Courts.
Tennis Courts is a reef break, fairly consistent, and it loves a swell from the SSE. The water temp is about average for the time of year, nothing wild there.
The best chance to score something is on Saturday, July 26th. The morning session looks the pick. We’ve got a 3 ft swell from the SSW, with a long period of 16 seconds. That’s a proper groundswell, packing a punch. The combined energy of all swells is a solid 879 (moderate), and the wind is a gentle cross-off breeze from the E at 12 mph. That’s going to keep the surface clean. It’s not huge, but with that period and a favourable wind, it should be the most rideable wave of the whole outlook. The swell is small enough for most, and the long period means better shape and longer lulls between sets. Crowds are sometimes an issue, so you might have some company.
The next decent call is Monday, July 27th, but it’s a different beast. The swell jumps up to 6 ft from the ENE, but the period is a short, choppy 7 seconds. The combined energy is high at 909 (strong), but it’s a short-period windswell. That’s a lot of water moving around with no real power or shape. The wind is a fresh cross-off from the ENE at 19 mph. It’s clean, but the wave quality will be poor. This one is for experienced surfers only if you’re out there, and honestly, it looks more like it’s set up for a good kite session.
Before that, Sunday, July 19th offers a bit of a teaser. A 6 ft ENE swell, but again, a short period of 8 seconds. The energy is moderate (497), and the wind is a moderate cross-off at 16 mph. It’s clean, but the wave quality is rated as poor. It’s a beach-and-reef setup, so with that short period and moderate size, it’s going to be a bit of a bumpy, walled-up mess. Not worth getting excited about.
So, the long and short of it: this is a tough 16-day forecast. There’s a massive gap of poor-to-marginal conditions from Wednesday, July 15th, right through to Friday, July 25th. The only real window is over the final weekend and into Monday. Saturday, July 26th morning, is your one true standout. It’s not perfect, but it’s the best we’ve got. Treat it as a promising but low-confidence bet this far out.
Rusty.
