The Lowdown
Alright, mate, Rusty here. Let’s look at what’s on the cards for the next couple of weeks.
Honestly, it’s a bleak outlook. A long stretch of flat, windy conditions, and pretty much nothing worth paddling for until the very end.
The first bunch of days are a total loss. From the 13th of July all the way through the 25th, it’s all tiny, weak swell—most of it under 2 feet—with fresh breezes from the south and southwest making it choppy and messy. The wave energy is pathetic, barely hitting the double digits (3 to 20 units). It’s a mix of cross-offshore and cross-shore winds, and the surf is just not happening. That’s a solid 12-day gap where you can leave the board in the garage.
The only time the ocean shows any sign of life is on the 26th of July, Sunday. In the afternoon, a little 3 foot swell from the south rolls in, with a period of 7 seconds. The energy bumps up to 80 units, which is still weak, but it’s the best of a bad lot. The wind goes glassy with a light breeze from the north-east, so it’ll be clean. The report says “surfable waves but very ordinary conditions,” and that’s about right. It’s not a standout, but it’s the only chance to get wet.
The spot is Coastguard Beach. It’s exposed to the south-east, so that south swell will wrap in, but the short period (7 seconds) means it won’t have much punch. It’s a consistent beginner break, and the water temperature is about average for the time of year at 67°F. Crowds are sometimes, so you might bump into a few others with the same idea.
After that, from the 27th onward, it’s back to tiny, poor surf with onshore and cross-onshore winds. Nothing to get excited about. This is a lean run—it’s just how it goes sometimes around here.
Rusty.

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