The Lowdown
Alright, Rusty here. Let’s break down what’s on the table.
It’s a lean stretch, no two ways about it. Devonport Rivermouth is a point/river deal, so it’s picky, and we’re looking at a solid gap of flatness before anything worth talking about shows up. From the 2nd of August through to the 8th, the swell is tiny – ankle to knee-high – with a mix of junk wind and poor conditions. There’s a brief moment on Monday afternoon the 3rd with glassy water and 1.4m from the NNW, but the period is short at 7 seconds and the energy is nothing special (197). Not worth the drive.
Then on the 9th of August, we get a jump in size – 2.1m in the morning and 2.3m in the afternoon, both from the NNW – but it’s blowing onshore with strong energy (502 and 565). Period is still short, so it’s a chaotic, choppy mess. That’s more of a kite-surfing show than a surf session. The week after that, from the 10th of August onward, things clean up but drop in size. Monday the 10th has clean, glassy-ish conditions with cross-offshore wind and 0.5m to 0.6m of NW groundswell (period 16–18 seconds). The energy is moderate (185 and 175), so it’s small but clean – okay for a longboard if you’re bored. Tuesday the 11th morning has 1.4m from the NNW again, but with a short 6-second period, so the shape will be average. That afternoon, it jumps back to 2.3m with onshore wind – messy again.
The best bet, if you’re really itching, is Monday the 10th of August. The wind is light and cross-offshore, the swell direction from the NW is ideal for the break, and it’s clean. But it’s tiny and inconsistent, so don’t expect much. Beginners can ignore this – it’s too small anyway. Experts will be eyeing the bigger pulses on the 9th and 11th, but the wind ruins those. Crowds are sometimes an issue here, but with surf this ordinary, you’ll have the place to yourself.
Water temp is 55°F, which is dead on average for this time of year. No surprises.
Bottom line: a very quiet 16 days. The first week is nearly a total loss. The second week has a few clean, small windows, but nothing to get excited about. If you’re a kiter, the 9th and 11th might have some fun. For the rest of us, it’s a waiting game.
Rusty.
