The Lowdown
Alright, surfers, Rusty here. We’ve got a bit of a mixed bag ahead for In-Betweens, a reef break that’s a beginner-friendly spot but pretty exposed. Water temps are sitting around 81°, which is pretty much spot on average for this time of year, so no surprises there.
The next 16 days are a bit of a waiting game, to be honest. The first few days are a washout, with poor surf conditions and not much to get excited about. We’ve got a long gap before things start to look interesting. The standout window is shaping up for Tuesday afternoon the 4th of August. That’s the one to circle. Swell energy is moderate (534), with a clean 5ft swell coming from the ENE, and a 11-second period which is a proper groundswell—that’s got some shape and power. The wind is light and cross-off from the NE, which is a major positive, meaning the wave faces will be super clean. For a beginner-friendly reef, this is about as good as it gets.
After that, it’s a bit of a slog. Wednesday the 5th is marginal, energy drops off and the size fades. From Thursday the 6th all the way through to the 13th, it’s a long stretch of poor conditions. The wind is mostly a fresh breeze from the ENE, keeping the waves cross-off but the energy is weak and the swell is just too small or messy to make it worth your time. The combined energy values are low to moderate (119 to 976), but the quality just isn’t there.
The next possible flicker is on Friday the 14th of August. The afternoon sees a bigger 8ft ENE swell with moderate energy (1101), but with a 8-second period, it’s a short-period wind swell, not a clean groundswell. The wind is a fresh breeze, so it’ll be choppy. At that size, In-Betweens being a beginner spot, this is really only for the experienced crew. After that, the end of the period dies out again with small, weak surf and poor conditions.
So, the call is clear: if you’re a beginner, your best bet is to wait for Tuesday afternoon the 4th of August. That’s the clean, glassy window. The rest of the fortnight is mostly a write-off, save for a couple of days that are more for the experts.
Rusty.
