Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
Alright, Rusty here. Let’s have a good hard look at what’s on the table, and I gotta be straight with you – it’s not looking great. We’re staring down a pretty bleak 16-day window for Coastguard Beach, with barely a ripple worth getting wet for. The whole period is basically a long, drawn-out stretch of flatness or junk, so you’re better off doing something else if you’re hanging for a wave.
Right out of the gate, the swell is pathetic. We’re talking 0.7ft on Sunday morning, 12 July, with a weak, short-period easterly windswell of 7 seconds. The combined wave energy is a measly 11 (weak), and the wind is cross-onshore. The surf is just poor and choppy. Monday and Tuesday are even smaller, at 0.3ft, despite some clean cross-offshore wind on Tuesday. The energy drops to just 3 (weak). The water temp is about average for this time of year, nothing wild.
Midweek, Wednesday 15 July morning shows a glimmer with a little offshore wind from the west, but the swell is still only 0.3ft and weak. By Thursday 16 July, there’s a tiny bump to 1ft from the SW with a period of just 4 seconds, and while the wind is offshore and clean, the combined energy is still weak at 11. It’s a skimboard day at best.
Then, we hit the first and only mentionable bump. On Sunday 19 July, the swell finally pushes to 3ft from the east, with a combined energy of 51 (moderate). The period is a real short 4 seconds, though, and the wind is blowing directly onshore from the east at 12-16 mph. This isn’t going to be pretty. It’s going to be a choppy, blown-out mess, and that size with onshore wind is not beginner-friendly but not real quality for anyone either. This is the only day that even registers on the scale, but it’s seriously compromised.
After that, the energy fades back into nothing. We see glassy conditions on the morning of Wednesday 23 July and again on Monday 27 July, but the swell is only 1ft to 2ft. The energy on the 27th is 37 (weak), with a period of 8 seconds from the SSE. The glassy wind is a huge positive for the look of the water, but there just isn’t enough push.
The rest of the 16 days is a sad story of 0.3ft to 2ft, weak energy values, and cross-on or onshore winds. The only real standout, if you can call it that, is Sunday the 19th for those absolute die-hards who just need to get wet, but with the onshore wind and weak period, the quality is going to be poor. For any sort of decent surf, this is a total write-off. You’re looking at well over two weeks of nothing worth paddling for. Given the lack of consistent swell and the poor quality when there is a bump, a blank run like this is pretty normal for the area, but it still stings.
Stay patient, keep an eye on the charts, and don’t get your hopes up for a while.

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.
