Devonport Rivermouth Surf Forecast and Surf Report

Alright, let’s put this in feet and miles per hour for you, mate.

First up, it’s a quiet scene out there for the first week and a half, to be honest. This spot is a point/river setup that’s known for being inconsistent, and this forecast is a real test of patience. We’re looking at a long stretch of flat to tiny waves with poor conditions, so you’ll be waiting a while for anything worth paddling out for.

The first real flicker of life doesn’t show up until Monday the 10th of August. We get a pulse of swell, but it’s a messy one. The combined energy of all swells directed here hits a solid 673 (moderate wave energy), with a 8ft swell from the NW. That’s a beefy size, pushing into expert-only territory and too big for beginners. The problem is the wind: a moderate cross-onshore breeze at 12-16 mph chopping it all up. The period is short at 8 seconds, so it’s not holding any quality shape. Honestly, this looks more like a kitesurfing setup than a paddle session.

Then, on Tuesday the 11th of August, things get a bit more interesting. The swell drops to 3ft from the NW, with a long period of 16 seconds – that’s proper groundswell energy. The combined energy jumps to 967 (moderate wave energy), which is the strongest we see. The morning is the best bet, with a gentle cross-offshore wind from the W at 9 mph. That’s going to clean the wave face up nicely. But remember, this is a river mouth and point break, so that long period swell will be lining up nicely, offering some good shaped waves with longer gaps between sets. The afternoon gets windier and rain showers move in, so the morning window is the stand-out.

The rest of the second week is a bit of a letdown. The swell drops back to under 2ft, but the windows on Thursday the 13th and Friday the 14th of August are worth a mention just for the peace. The water temp is about average for the time of year, and with glassy, clean conditions, you’ll have a very quiet, reflective session on the little ankle-biters. The crowds are “sometimes” an issue here, but on these days, you’ll be lucky to see anyone else.

So, the one true stand-out is the morning of Tuesday the 11th of August. It’s the biggest, cleanest, and most powerful swell in the whole run. It’s a long-range call, so don’t set your watch by it, but it’s the one to circle on the calendar.
