Devonport Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you – things are looking pretty quiet for Devonport Rivermouth over the next couple of weeks, with no real standouts to get too excited about. The water temp is sitting at 55°F, which is about average for this time of year around here.

The outlook starts on Monday the 7th of September, but don’t get your hopes up. We’ve a tiny 0.7ft of WNW swell, but with a period of 11 seconds, it’s got a little groundswell energy behind it. Combined swell energy is weak at 16, and the WSW 10 km/h cross-off breeze will keep the surface clean. Still, it’s just too small to bother with.

Tuesday the 8th stays flat in the morning with only 0.3ft, and by the afternoon a 5ft NW windswell comes in with a short 6-second period. That’s a messy 140 combined energy, but the 25 km/h WNW crosswind will chop it up. Not worth a paddle.

Wednesday the 9th and Thursday the 10th bring tiny NW groundswell pulses – around 1.0ft to 1ft with periods up to 19 seconds. Sounds nice on paper, but the energy is weak (60 to 105), and the size just isn’t there. Thursday morning gets a score of 1 out of 10 for “surfable waves but very ordinary conditions,” but honestly, that’s being generous.

From Friday the 11th right through to the 18th of September, it’s a long stretch of tiny waves. Swell hovers between 0.3ft and 1ft for most of that time, with periods ranging from 5 to 19 seconds. The wind is mostly cross-off or cross, with a few glassy moments on Sunday the 13th morning – 0.3ft and NE 5 km/h glass, but you’d be hard-pressed to ride anything. The combined energy rarely gets above 70. There’s a little pulse on Monday the 14th afternoon: 6ft from the NW with a short 6-second period and 282 combined energy, but a 35 km/h WNW crosswind will thrash it. That’s more of a kite session than a surf.

A bit more size shows up on Saturday the 19th of September. We’ve got 7ft to 7ft from the NNW, period of 8 seconds, and combined energy jumping to 586 in the morning and a whopping 1173 in the afternoon. That’s strong energy, but the wind is cross-shore from the NW at 10 to 20 km/h, creating a bit of chop. The size is getting up there – over 5ft, so it’s not ideal for beginners, and with that short period it’ll be lumpy. Marginal surf conditions is the call. If you’re an experienced local and don’t mind a bit of mess, the afternoon might have some grunt, but it’s not the clean, lined-up gem we’d hope for.

From the 20th to the 22nd, we fade right back to tiny 1.0ft to 1ft NW swell with weak energy and cross winds. A blank run like this is more normal for this area, and honestly, the forecasts could change for the better. Keep an eye on the 19th as a maybe, but don’t cancel your plans.

Rusty.
