Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
Alright, Rusty here, and I’ve got to be straight with you – the surf outlook for Coastguard Beach is a tough one. Right now, and for the next 16 days, there’s just nothing to get excited about. All the signs point to poor surf conditions, day after day.
The water temperature is sitting at a pretty average 65°F, nothing unusual for this time of year.
We start with a bit of a flat spell. On Friday the 10th and into Saturday the 11th, there’s almost no energy in the water. The combined swell energy is in the weak range (31 and lower), with tiny waves around 0.3m to 0.6m. Even the wind tries to help out with some light breezes, but the swell just isn’t there. You’d be spending more time paddling than riding.
Then we hit a long, dry gap. From Sunday the 12th all the way through to Sunday the 19th, there’s a stretch of minimal or no surfable waves. The energy readings are painfully low (3 to 45), with swell heights mostly under 0.4m. The wind does offer some clean, offshore moments on a few mornings and afternoons, like Monday the 14th and Thursday the 16th, but with wave heights of just 0.1m, it’s a total non-starter.
Finally, around Monday the 20th, we see a bit of a lift. The swell picks up to 1.4m from the east, and the combined energy jumps to 236 – that’s a moderate surge. But here’s the catch: the wind is onshore, blowing right into the face of the waves, making them choppy and messy. The period is short at 6 seconds, so it’s just wind-slop. It’s not really paddle-surfable; that kind of setup is honestly more of a kite-surfing day.
That pattern stays rough through the rest of the period. We see a bit more size on Friday the 24th (1.1m from the south, energy 169) and Saturday the 25th (1.0m), but again, the wind is cross-onshore and the conditions are described as poor.
So, what’s the best of a bad lot? Honestly, there are no standouts. The most interesting moment is Monday the 20th and the surrounding days, but only if you’re chasing a messy, onshore bump with no quality. For clean, rideable surf, there is nothing on the table. It’s a blank run for the books, but for Coastguard Beach, that’s not totally abnormal. Forecasts can change, so don’t lose hope entirely.
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.
