Alright, Rusty here. Let’s have a look at what’s coming down the line for Rivermouth.

Alright, so the next couple of weeks at Rivermouth are a bit of a mixed bag, but there are some real gems hiding in there if you’re patient. The water is sitting at 64°, which is much colder than we’d expect for this time of year, so you’ll want a decent wetsuit.

We’re starting off with some solid swell, but the conditions are a bit messy. The first real highlight isn’t until Monday the 13th. That morning, the wind drops to nothing – glassy as a mirror – with a 6ft swell from the ESE. The combined energy is moderate at 622, and it’s a clean, fun size for a beginner-friendly spot. The afternoon holds a similar vibe with 5ft and glassy conditions, but the energy drops a bit to 490.

Tuesday the 14th is another cracker. Another glassy morning, with 6ft of E swell and moderate energy at 500. It’s clean and inviting. The afternoon has wind turning onshore, so get your session in early.

Wednesday the 15th starts glassy again with 5ft E swell, energy at 448. Good, clean waves for a cruisy session, best for beginners.

Now, the big one. Saturday the 18th and Sunday the 19th see a big jump in size. Saturday morning, the swell hits 7ft from the SSW with a strong energy reading of 1009, but it’s howling a 19 mph wind. That afternoon, it jumps to 10ft with massive energy at 2979, but the wind is still fresh. This is strictly for experts only – too big for beginners. Sunday the 19th brings 10ft of S swell with very strong energy at 3201, and the morning is glassy. But again, that’s big, powerful groundswell with a period of 14 seconds. It’s going to be a serious paddle, and at a river mouth, it could be a bit tricky.

The final standout is Wednesday the 22nd. A 8ft S swell with a very long period of 18 seconds – that’s a proper groundswell. The energy is huge at 3695. The wind is a cross-shore 9 mph, keeping it clean. This is another one for the experienced crew only, as the size and power will be intense.

Overall, the best all-rounder for most surfers is the glassy mornings on Monday the 13th and Tuesday the 14th. For the big-wave hunters, Sunday the 19th and Wednesday the 22nd are the ones to circle on the calendar, but be prepared for a serious session. Crowds are likely at Rivermouth on the good days, especially when it’s clean.

Rusty.

Information about the Rivermouth Surf forecast

The above surf forecast table for Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
