The Lowdown
Alright, let’s see what the ocean’s got cookin’ for us here at Rivermouth.
The next week and a half is a bit of a mixed bag. We got some waves on the way, but the wind is going to be a player in how good it actually gets. The first few days are looking pretty average, with cross-shore breezes messing with what would otherwise be a fun little pulse of east-southeast swell.
Sunday the 2nd brings in a 8ft easterly-southeast swell with a 12-second period, but that moderate cross-shore breeze is going to have it a bit jumbled. The energy is strong (1666 combined), but it ain't gonna be clean. Monday the 3rd drops a touch in size to 7ft, still with that cross-shore wind, and the period shortens to 11 seconds. It's still surfable, especially for the more forgiving crew, but it's not going to be a classic.
Tuesday the 4th and Wednesday the 5th see the swell ease off and the wind stay cross-shore. Tuesday morning has some 5ft waves, but it’s not going to be pretty. Wednesday morning the wind actually turns a touch cross-offshore and it cleans up a little; 4ft and a bit more shape. A half-decent window for a quick session if you've got the flexibility.
Then we hit a bit of a flat spot from Thursday the 6th through to Saturday the 8th. The swell drops right out. Thursday morning is tiny and messy, practically nothing. Friday the 7th has some new southerly swell showing at 3ft but it's short-lived and the energy is weak. However, Friday morning looks glassy before that afternoon breeze picks up. Saturday the 8th is similar – a little 3ft south swell and that period pushes out to 14-15 seconds. It's clean in the morning, but it's going to be small and weak.
Right, now here is the standout, and it's a big one. Sunday the 9th, the ocean is going to wake up. The swell is forecast to be a solid 13ft with a shorter 13-second period, and the energy is a punchy 6713. This is a serious amount of water, and at Rivermouth, it's going to be too big. It'll be a walled-up mess, dangerous and not really paddle-surfable. The wind and tide might be favorable, but don't be a hero. This is more of a spectator event, or maybe one for the tow crew if they're out there. There's a definite drop-off in energy later that afternoon, but it's still big. The following days, Monday the 10th and Tuesday the 11th, are still stormy and messy, with onshore winds and rain. Not a good look.
Now, Thursday the 13th is the other date to circle. The swell is still up there – 12ft – but the wind is forecast to swing offshore from the northwest. The energy is still strong (3106) and while this is definitely big and only for the experts, the offshore wind will make for some clean, powerful walls. This is the one for the big-wave chargers.
Friday the 14th is the last real shout. The swell has backed off to 7ft, still with that NW offshore wind in the morning. It's going to be clean and have some push to it. The energy is moderate (1154), but it's the most user-friendly size with offshore winds we see in the whole period. This is probably the best call for most of you who want to get out there and have a proper session.
After that, it's a slow fade. The weekend drops off, and by Monday the 17th, we're looking at ankle-biters.
So, for the best of it, you're looking at two windows: Friday morning the 14th for the clean, manageable swell, and if you're a proper charger, Thursday the 13th for the big, clean, offshore day. The 9th is just too big and messy. Water temp is running pretty normal for this time of year, so nothing wild there.
Keep an eye on the forecasts, as things can shift, but that's the lay of the land for now.

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.
