The Lowdown
Alright, Rusty here. Gonna level with you: the next 16 days at In Betweens are a tough stretch. Lots of small, choppy wind swell and those pesky cross-off breezes hanging around. Water temp is normal for the time of year.
Your first actual chance to get wet isn’t until the morning of Monday, July 20th. Even then, it’s a borderline call. You’re looking at a tiny 2ft S swell with moderate energy (582). The wind is a moderate cross-off, so it’ll be clean, but it’s hardly worth waxing up. The swell is coming from the south, and this reef really likes a SSE direction, so don’t expect much.
Things stay marginal through the week. The best shot of the whole forecast looks like the morning of Saturday, July 25th. We’ve got a 3ft SSW groundswell with a 19-second period, and a moderate cross-off breeze from the NE at 12 mph. The combined energy is strong (793). That long period means the waves will have some real push and shape, but on a reef, it might get a bit walled. It’s the clear standout, but it’s still a small wave.
The morning of Sunday, July 26th is the next best, with a 3ft SSW swell (16 seconds) and a moderate breeze. Energy is still strong (879). Crowds are sometimes a thing here, so you might have company.
After that, it gets messy. By Monday, July 27th, we get a bump in size to 6ft, but it’s all short-period (7 seconds) ENE wind swell with a fresh cross-off breeze. The energy is very strong (909), but the short period and angle will make it a bumpy, close-out mess. Not worth it. The rest of the outlook is back to poor conditions with tiny, weak swell.
So, bottom line: circle the morning of Saturday, July 25th. It’s the only real highlight in a long stretch of meh. Everything else is a gamble.
Rusty.
