Updates in hr min s Forecast update imminent
Alright, let’s break it down, metric to imperial. Rusty here, same spot.
Water temp is about 64°, which is roughly 4° cooler than average for this time – that’s a noticeable drop, you’ll feel it.
We start off slow. Sunday July 5th through Tuesday July 8th are mostly small and wonky. Sunday morning has a 5ft SE groundswell at 12 seconds with a light offshore breeze, clean, but the energy is moderate (634). Surfable for beginners, but nothing crazy. The rest of those days are ordinary to poor with light onshore winds and tiny waves.
Wednesday July 9th picks up to 7ft to 7ft S swell at 13 seconds, but cross-shore winds leave a slight chop and energy jumps into strong range (1666 to 2921). Messy.
Best day: Friday morning, July 10th. Rivermouth gets a clean 8ft S swell with a 14-second period (long-period groundswell), and it’s glassy – S wind at just 3 mph, dead calm. Energy is very strong (2367). This will produce clean, powerful waves. At 8ft, that’s expert territory – too big for beginners. Crowds are possible, so expect some company. This is the clear standout.
After Friday, the swell hangs but the wind turns ugly. Saturday July 11th and Sunday July 12th have 6ft to 4ft SSE to S swell, but onshore and cross-onshore winds from the ENE with moderate energy (568 to 1056) chop things up. The following week has more builds and drops, with a 7ft SSW swell on Monday July 13th afternoon (clean cross-off, strong energy at 1472) and a 7ft SSW swell on Tuesday July 14th morning (clean but strong wind at 19 mph, energy 1305). Not bad, but wind is punchy.
Wednesday July 15th morning turns glassy again with a tiny 4ft E swell at 10 seconds (moderate energy 429), clean but small. Then it fades to moderate or poor surf through the rest of the week.
Looking out, Friday July 17th morning has a 8ft SSW swell at 10 seconds with cross-shore winds and energy at 2111 (strong) – surfable but choppy. Then Saturday July 18th morning pumps up to 10ft S swell at 9 seconds with 2640 energy – very strong, but the break is noted as being too big for Rivermouth. Only experts should even think about it.
Sunday July 19th and Monday July 20th have S swell dropping from 5ft to 3ft, with lighter winds but cross-on and cross conditions – nothing special.
Your best bet is Friday July 10th morning. Clean, powerful, and the standout of the whole forecast. After that, you're hunting for windows between the wind shifts.
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.
