Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
G’day, Rusty here. Look, I’ve poured over the charts for this stretch of coast, and I gotta level with you – it’s a long, grim grind. The whole 16-day outlook has barely a pulse. There’s a massive gap of over a week with nothing worth mentioning before one single afternoon shows a bit of life.
The only break we’ve got to talk about is Coastguard Beach. Water temps are running 68°F, which is a touch warmer than usual for this time of year – a small mercy if you’re not a fan of a thick wetsuit.
From July 9th right through to July 17th, it’s a complete washout. Tiny, weak dribble under 2ft with mostly onshore or side-shore slop. The combined energy is laughably low, barely ticking over (between 4 and 35). Don’t bother.
The one and only bright spot pops up on Saturday, July 18th in the afternoon. The swell comes in around 6ft from the south, with the combined energy jumping to 374 – that’s real, proper push. The wind is light from the southwest, making for a clean, cross-off breeze. It’ll be surfable and punchy. But the period is only 7 seconds, so it’s a short-period, wind-driven pulse, not a classic long-period groundswell. At this size, it’s beyond beginner territory and into the fun zone for experienced surfers. Expect a bit of close-out action at a beach break, but it’ll have some decent welter. There’s "sometimes" a crowd here, so don’t be surprised to see a few others on it.
From July 19th onward, it’s back to tiny, weak dribble. July 23rd morning has a whisper of offshore wind and a bit of 3ft east swell, but the energy is still only 73 and the quality is ordinary.
So, here’s the call: if you need a surf, the only window is the afternoon of July 18th. It’s a short, clean south swell that’ll give a couple of fun corners. Everything else is a blank run. Stay patient.
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.
