Devonport Rivermouth Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s break down what’s in store for Devonport Rivermouth (point/river) over the next couple of weeks.

Right from the start, the next few days are a total bust. Tuesday the 15th and Wednesday the 16th have barely any surf – tiny 0.3ft to 1ft NW swell with combined energy from 19 to 84 (weak). The wind’s cross-off or offshore, so the water’s clean, but there’s nothing to ride. Thursday the 17th is more of the same: 0.7ft to 1.0ft NW swell, energy dropping to 34 and then 20 (weak). It’s a dry spell for the first three days.

Friday the 18th brings a little more size, but don’t get excited. Swell hits 4ft in the morning and 5ft in the afternoon out of the WNW and NW, but the period is a short 5 to 6 seconds, and the wind turns cross-shore. Energy climbs to 95 (weak) then 160 (moderate), but the waves are lumpy and chopped. Saturday the 19th is similar: 4ft to 5ft NW swell with short period, energy at 131 and 161 (moderate), but cross-off wind in the morning cleans it up before the afternoon cross-shore ruins it.

Sunday the 20th is where things get a bit rowdy. The morning serves up an 8ft NW swell with a 7-second period, combined energy at 754 (strong). Wind is light cross-onshore, so it’s marginal. This is expert-only territory over 8ft, and the short period means it’s going to be dumpy – not for beginners. The afternoon blows up with 10ft NW swell at 9 seconds and a fresh cross-shore wind, energy hitting 1246 (very strong), but conditions are poor and lumpy. Honestly, this is more of a kite-surfing day than a paddle session.

After that, Monday the 21st through Thursday the 24th drops right back down. Swell sizes from 1.0ft to 3ft, mostly NW or NNE, with weak energy (26 to 65). A few glassy moments on Wednesday the 23rd and Thursday the 24th afternoon, but the waves are tiny – not worth suiting up for.

Friday the 25th is a small bright spot. Morning brings 4ft NW swell at 5 seconds, combined energy of 145 (moderate), and glassy conditions. It’s surfable but very ordinary. The afternoon gets a light cross-onshore and quality drops.

Saturday the 26th morning has a 1ft NW swell but with a long 16-second period, energy at 162 (moderate), and glassy wind – so it’s clean, but tiny. That long-period groundswell is better for point setups like this, but there’s just not enough size. The afternoon bumps to 2ft NW swell with a 19-second period and energy of 242 (moderate), but onshore wind kills it.

The rest of the outlook into late September and the 30th is mostly small, weak, and clean but unsurfable. A few glassy mornings with 1ft to 2ft NE or NNE swell, but combined energy is under 60 (weak).

If I had to call a standout, it’d be Sunday the 20th morning – but only for experts who can handle a big, lumpy 8ft NW swell. Even then, it’s marginal. For everyone else, this is a flat and quiet stretch for Devonport Rivermouth. We’ll need a change in the pattern to get anything worth paddling for.

Stay patient, and keep an eye on the sky – it never stays this flat forever.

Rusty.
