The Lowdown
Alright folks, this is Rusty, and I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. We’ve got Coastguard Beach as our only option on the table, and it’s just not firing.
Looking at the whole 16-day window, there’s basically nothing worth getting wet for. The swell is tiny, the energy is weak, and the conditions are all over the place. The combined energy of all swells directed here is mostly a measly 3 to 24 (weak energy), which tells you everything you need to know. You’re looking at a whole lot of flat spells.
Let’s break it down. The water temperature is sitting at 67°F, which is about 1°F cooler than normal for this time of year – nothing wild, just a touch on the fresh side.
Starting off Friday, August 7th, we’ve got a tiny 0.3ft swell from the SE with a short period of 8 seconds and a cross-off wind. It’s clean, but it’s barely a ripple. Saturday and Sunday are more of the same – 0.3ft to 1ft of weak, short-period slop. Sunday morning has a light offshore wind, which is nice, but there’s just no energy to work with. The whole first week is a bust. Even when we get a glassy morning on Wednesday, August 12th, the swell is a pathetic 1ft. The energy is climbing a bit, hitting 15, but that’s still laughable.
The second week doesn’t offer any relief. There are a few windows of clean conditions, like Thursday morning, August 13th with glassy conditions, but again, the swell is 0.3ft. Friday, August 14th brings the biggest swell of the whole period at a whopping 2ft, but it’s short period (4 seconds) and onshore. Saturday the 15th has some 1ft swell with moderate cross-off winds, but it’s just not enough push. Just a long stretch of tiny, weak surf.
The only real standout in terms of conditions is the morning of Saturday, August 22nd, when we get a glassy, clean 1ft swell. But again, it’s tiny. The energy is only 15. For a beginner, even that 2ft might be a fun little splash, but for anyone else, leave the board at home.
With such consistent tiny surf and a lot of those cross-off winds, if you’re feeling the itch, the setup at Coastguard Beach looks more interesting for a kite session than a paddle session. Honestly, it’s a bleak run. This kind of blank period can happen, and forecasts can change, but right now, there’s nothing to get excited about.
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.
