The Lowdown
Alright, this is Rusty checkin' in with a look at what's cookin' for Coastguard Beach. We've got a real quiet spell on our hands for the foreseeable future, so don't be in a rush.
The whole 16-day window is pretty flat and sleepy. There's a big gap of nothing worth paddling out for right from the start. The first time we see any real energy showing up is on the 22nd of August, but even then it's not much to write home about. Before that, it's just tiny dribbles and junk.
On the 22nd of August, Saturday morning, we finally get something that could be called surfable, but just barely. Swell is a measly 2.3ft from the SE, with a moderate energy level (145). It's clean with a light cross-offshore breeze, so the surface will look alright. But the wave quality is still described as very ordinary, so you're not missing much.
The 23rd of August, Sunday morning, is the pick of a very weak bunch. Still small at 2.6ft from the E, but the energy is similar (135) and we get a strong cross-offshore wind that will keep the face clean. It's not gonna be a day for the highlights reel, but if you're desperate for a paddle and a few little ones, it'll be the best of the lot.
The water temp is sitting around 69°, which is about average for the time of year here, so no need for a thick suit.
Honestly, this is a blank run for Coastguard Beach. It's a spot that doesn't see a lot of action, and this forecast just confirms that. Keep your board in the car and wait for a better day. Forecasts can change, but right now, it's a waiting game.

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.
