The Lowdown
Alright, this is Rusty, and I’ve got the long-range picture for Campbells.
To be straight with you, this forecast window is a tough one. We’ve got a long stretch of mediocre to poor conditions, with the only real window of opportunity arriving this coming Thursday. For the most part, the wind is going to be a pest, and the swell is going to be small, making it a waiting game. The first good surf doesn't show up until Thursday, the 20th of August.
The water temperature is sitting at a warm 81°, which is about average for this time of year, so no need for a thick wetsuit.
Thursday the 20th is the standout session. Morning and afternoon both look good, with glassy conditions as the wind drops to near nothing. The swell will be small, around 2 feet from the SW, but with a nice long period of 17-18 seconds, meaning proper groundswell energy. The combined energy is moderate, reading at 356 in the morning and 344 in the afternoon. This is a reef break that loves that SW direction, so the shape should be fun despite the size. You’ll also want to note that this spot is inconsistent, so don't expect a wave every minute, but when they come, they’ll be clean and lined up. Crowds are often an issue here, so with such a small window of quality, expect company.
After that, Friday the 21st is a write-off with cross-shore wind messing things up. Saturday the 22nd morning has a bit of potential with a cross-offshore breeze and a bigger energy reading of 484, but the afternoon gets hammered by a strong cross-offshore wind. From Sunday the 23rd onwards, it’s mostly blown out, with strong to fresh winds from the ENE dominating. The swell stays small, mostly around 2 to 3 feet, and the energy readings bounce around, but the wind just ruins it.
There’s a glimmer on Friday the 28th of August with a moderate offshore wind and a clean forecast, and a 3 foot swell from the S, but it's a one-morning stand before the wind shifts again.
Basically, if you can paddle out Thursday, that’s your best bet. The rest of the two-week window is one to watch from the beach or pick up another hobby.

Information about the Campbells Surf forecast
The above surf forecast table for Campbells provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Campbells can be found by selecting the local surf guide option on the grey menu. Our Campbells 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 (Campbells) 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 Campbells 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.
