Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
Alright, let’s talk surf. This is Rusty, and I’m looking at a pretty grim stretch ahead for Coastguard Beach. To be honest, there’s nothing really worth getting wet for in the next 16 days. The first sign of any kind of rideable wave doesn’t show until the morning of Friday the 25th of July, and even that is pretty ordinary.
The pattern for the whole period is small, wind-affected, and mostly just poor. We’re talking a whole lot of flat, messy days. From now through to around the 22nd of July, it’s mostly tiny dribble with onshore or cross-off winds that ruin what little is there. There’s a gap of almost two weeks with absolutely no recommendation worth mentioning. The water temperature is around 65°, which is pretty much normal for this time of year.
For the one faint glimmer we have, let’s look at Coastguard Beach. On the morning of Friday the 25th of July, there’s a tiny 2ft swell sneaking in from the SE with a period of 9 seconds. The combined swell energy is weak (63). The wind is light offshore from the W at 6 mph, which will keep things clean, but honestly, it’s surfable waves but very ordinary conditions. The waves are small, the energy is low, and while it’s not blown out, there’s nothing exciting about it. It’s a beginner wave at best, and crowds are sometimes a factor here.
Don’t get your hopes up. The second week of the outlook is more of the same – small, choppy, and barely worth a look. The setup is more interesting for a kite surfer than a paddle surfer on most days, especially around the 22nd and 24th when the wind gets strong and cross.
Stay patient. Forecasts can change, but right now, we’re in a dry spell.

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.
