The Lowdown
G’day, Rusty here. Let’s talk about what’s happening at Rivermouth over the next couple of weeks.
We’re in for a slow start. The first few days are a bit of a mess. Saturday and Sunday the 1st and 2nd of August have chest to head-high swell, about 5ft to 8ft, but it’s all cross-shore wind with a chop on it. Monday the 3rd is more of the same – lumpy and cross-shore, with the swell dropping to around 6ft to 6ft.
Tuesday morning the 4th of August brings a small window. The wind turns light cross-offshore, and the swell is a clean 5ft from the ESE, with a 10-second period. The crowds are possible here, so don’t expect solitude.
Then we hit a dry patch. From Wednesday the 5th right through to Saturday the 8th, the conditions are poor. The swell drops, the wind is messy, and there’s a big 10ft lump on Thursday the 6th, but it’s coming with a fresh cross-shore wind and a chop. If you’re into kiting, that Thursday afternoon with 10ft and a fresh breeze might be more your thing.
Now, here’s the real highlight. Sunday the 9th of August. The morning is a beauty. We’ve got a 7ft SW groundswell with a 14-second period, and the wind is glassy – dead calm. The report says “excellent surf conditions for experienced surfers.” This is the one to save the date for. The afternoon gets too big at 12ft with a short period, so it’s just the morning window.
Monday the 10th and Tuesday the 11th are a write-off. The swell is huge, 20ft to 21ft, but the wind is a strong cross-onshore mess with rain. It’s a big, ugly, blown-out ocean.
The following week is a bit of a mixed bag. Wednesday the 12th to Friday the 14th of August see waist to chest-high swell around 6ft to 8ft, but the wind is still cross or cross-onshore, and the conditions are only marginal. There’s a moment on Thursday the 13th morning with 10ft and glassy wind, but it’s too big for the break.
Finally, Sunday the 16th of August gives us a clean little finisher. The morning has a 5ft swell from the east, with a light cross-offshore breeze and clean conditions. It’s not big, but it’s rideable.
So, the standout is the morning of Sunday the 9th of August. Set your alarm, get down there early, and enjoy that glassy, long-period groundswell. The rest of the window is a mix of marginal and blown-out surf.
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.
