Devonport Rivermouth Surf Forecast and Surf Report

Alright, Rusty here, let’s look at what’s on the table for the next couple of weeks.

To be honest, it’s a pretty bleak stretch for Devonport Rivermouth (Tasmania). The whole 16-day window is a struggle, with only one real standout session that gets the nod.

The best chance you’ll get is Wednesday morning, August 12th. The swell comes in at 6 ft from the NW with a short period of 7 seconds, giving the water a bit of push—combined energy is moderate at 402. The wind is blowing cross-off from the WSW at 16 mph, which should keep the surface clean. It’s a point/river setup, so that NW swell finds its way in, but this spot is inconsistent and can be picky, and with a beginner-friendly difficulty, it's not a heavy wave. Crowds are possible here sometimes. The water temperature is about average for this time of year.

After that, the surf drops right off. Thursday the 13th through the end of the month is mostly flat or tiny, with poor conditions and scores that don’t get the blood pumping. There’s a long gap of nothing worthwhile. The combined energy falls away to weak numbers, often under 100. Winds are messy or onshore, and the swell heights are fractions of a foot.

One thing worth watching: on Sunday morning, August 23rd, there’s a glassy, dead calm morning with a very long-period swell from the NNW at 21 seconds and a tiny 0.7 ft. That’s not going to break for a paddle surfer, but it tells you there’s a deep groundswell pulse in the water. The next day, Monday the 24th, has a glassy afternoon with a 1.0 ft NW swell and 16-second period, but again, too small to bother with.

The short-period swells that pop up around the 18th and 25th are in the 4 ft to 5 ft range from the NE and WNW, but with periods under 8 seconds, the waves are weak and crumbly, and the wind is cross or onshore, so it’s a messy affair. Honestly, for a beach-and-reef setup like this, those conditions look more interesting for a kite surfer than a paddle surfer.

Bottom line: Wednesday morning the 12th is your one shot. After that, you’re waiting a long time. Forecasts can change, but right now, it’s a quiet spell.

Rusty.
