The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
To be straight with you, the whole 16-day window is a bit of a bummer. There’s a long stretch of flat, poor conditions, especially from the start. The first bit of any real surfable energy doesn’t show up until the 28th of July, and even then it’s nothin' to write home about. You’re lookin’ at a solid five-day gap of tiny, weak waves before we get a pulse.
The standout—and really the only period worth paddling out for—is the afternoon of Tuesday the 28th of July at Coastguard Beach. We’ve got a 4ft swell pushin’ in from the SSE, with a period of 5 seconds. That’s a short-period, locally wind-driven wave, so it’ll be a bit crumbly, but the energy is moderate (104) and the wind is light and cross-shore from the south at 6 mph. That means small crossing wind ripples, but clean enough for a beginner spot. It’s not gonna be a day for the pros, but for a log or a foamie, it’s your best bet. The water temp is about average for this time of year.
Before that, the morning of the 28th is smaller (3ft) and the afternoon of the 27th of July has a clean look with a 3ft swell from the ESE and a moderate cross-offshore breeze, but the energy is weaker (116) and the swell is messy. The 29th of July afternoon has a 3ft swell from the ENE with moderate energy (127), but the wind is onshore and choppy, so it’s a pass.
After that, it’s back to tiny dribble. A few clean mornings pop up around the 30th and 31st of July, and again on the 2nd and 4th of August, but the swell heights are all under 3ft, with weak energy (mostly under 100). The 4th of August morning has a glassy, offshore wind from the WSW with a 2ft swell from the S, but the period is short (6 seconds) and the energy is low (41). You’d be scratchin’ for a ride.
So, bottom line: if you’re desperate, the afternoon of the 28th of July is the time to go. Otherwise, it’s a long wait. This stretch looks more interesting for a kite than a paddle. Keep an eye on the forecasts, though—it tends not to stay this flat forever.
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.
