Table - best surf conditions forecast for Rivermouth over the next 16 days.
Alright folks, Rusty here. Let’s get into it. We’ve got a decent run of surf on the way at Rivermouth, but you’re gonna have to be patient through a few iffy days. The real star of the show is looking like the final weekend – stick with me.
The week kicks off on Sunday, July 12th, with a bit of a mixed bag. The morning is the pick, with a clean 4ft south swell, a very long 12-second period. The water is a very chilly 64°, a massive 4° colder than usual for this time of year, so definitely bring the thickest wetsuit you’ve got. Winds are glassy, making for some really nice, clean lines despite the modest size. The combined wave energy is moderate (818). The afternoon goes a bit pear-shaped as the wind comes onshore.
Monday the 13th serves up a bigger 7ft east swell, but the period is short at 8 seconds, and winds are cross-shore. This makes for a lumpy, unappealing mess. For Tuesday the 14th, the swell drops back to a more manageable 6ft from the east, but the winds are glassy, so the morning session in particular will be clean and worth a paddle. The energy is moderate (519).
Wednesday and Thursday the 15th and 16th are smaller and a bit scrappy. Then Friday the 17th gets interesting with a 5ft SSW groundswell with a long 14-second period, but a 19 mph cross-offshore wind makes it a battle and the energy is strong (1220). It’s not the cleanest. The 18th is a write-off with messy onshore winds.
Now, here’s where it gets good. Sunday the 19th shows a nice 5ft SSE swell with a long 13-second period and clean winds. The energy is strong (1083). Then Monday the 20th morning has a clean 4ft east swell with moderate offshore winds from the NW. It's not huge, but it's tidy.
After a few poor days mid-week, we get the real standout on Saturday, July 25th. The morning is firing. A clean 5ft SSW groundswell with a very long 16-second period, offshore winds from the NW, and the water is back to being glassy. The combined wave energy is very strong (1271). This is excellent, powerful surf for experienced surfers. The swell direction is a perfect match for what Rivermouth wants. This is the one to circle on your calendar, although it is a couple of weeks out, so keep an eye on it.
Sunday the 26th has plenty of leftover energy (1178) from the same long-period SSW swell at 5ft, but the wind goes cross-shore, taking a little shine off it. And finally, Monday the 27th wraps things up with a pumping 7ft SSW swell (2285 combined energy) and a 16-second period, but the cross and cross-onshore winds will chop it up.
Keep that 25th in mind, boys. That’s the one. The run from the 25th through the 27th looks like the best window, but the 25th is the cleanest.
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.
