The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
To be straight with you, the next two weeks are looking pretty flat and pretty grim. We’ve got a long stretch of small, weak, and messy surf ahead at Coastguard Beach. From now until the 20th of July, there’s really nothing worth paddling out for – just a lot of tiny, wind-affected dribble. The best you’ll see is a few small pulses around the 1ft to 2ft mark, but the wind is mostly cross-off or cross, and the energy is pitiful, often in the single digits or low double digits. It’s a tough run.
The first hint of something surfable pops up on Monday, July 20th, in the morning. Swell is a tiny 2ft from the SSE with a period of 9 seconds, and the combined energy is still weak at 67. The wind is light and cross-off from the NW, so the surface will be clean. It’s surfable, but it’s very ordinary. Not a stand-out by any stretch.
Wednesday, July 22nd, sees a bit more size pushing in – 2ft from the SE, period of 9 seconds, energy up to 89 – but the wind is cross-off in the morning, keeping it clean. In the afternoon, the wind turns cross-onshore, and it gets choppy. Still not a great session.
The best chance in this whole run looks like Thursday, July 23rd, in the morning. Glassy conditions with a light N wind, 2ft of SE swell at 9 seconds. The energy is 83. It’s small, but it’ll be the cleanest the waves will be all week. If you’re desperate for a paddle, that’s the window.
After that, Friday July 24th morning has a pulse of 3ft from the SSE with a short period of 7 seconds, and the energy actually jumps to 145 – moderate energy for a change. But the wind is onshore from the ESE, making it choppy. Not great, but it’s the most energy we’ll see.
Nothing else in the second week looks worth blocking out time for. The swell stays tiny, the wind is mostly onshore or cross, and the scores are all zero or one. If you’re a kite surfer, some of those breezier afternoons might look interesting, but for a paddle surfer, it’s a write-off.
Water temperature is 68°F, which is a touch warmer than usual for this time of year.
Stay patient, folks. It’s a quiet spell.

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.
