The Lowdown
Alright, I’m Rusty, and I’ve stared at this stretch long enough to know when it’s worth paddling out.
Right now, we’re looking at a rough 16-day run. The first 10 or 11 days are basically flat and a write-off for any proper surf. You want to surf, you’ll be frustrated. The swell just isn’t there, and when a little bump shows, it’s short period, weak, and mostly messy.
Across this whole stretch, the water temp is sitting around 66°F, which is about spot on for this time of year – nothing unusual for mid-July.
The very first hint of anything surfable comes Sunday, July 19th in the afternoon. We finally get a bump up to 4ft from the SSW, but the period is a short 8 seconds and the energy is moderate (248). It’s a south swell but the wind is cross-off from the NNW, so it stays clean. The score is only marginal though – not exactly screaming epic.
After that, it’s back to tiny slop for days. There’s a faint flicker on Friday, July 25th afternoon with 4ft from the S and a 6-second period, but the energy is moderate (142) and it’s cross-onshore, so you’ll be battling chop.
The only real standout, if you can call it that, comes Sunday, July 26th in the morning. We get 2ft from the SSW, a 7-second period, and glassy conditions. That’s rare – glassy and clean with the wind swinging SE and becoming near calm (3 mph). Energy is weak (77), but for a beginner spot that’s consistent, it’ll be a rare clean session. Keep expectations low on size, but dawn patrol will have smooth faces.
The rest of the run through the end of July stays small – 1ft to 3ft – with short periods and cross-off winds. It’s not terrible for a beginner to float around, but don’t expect a proper wave.
Honestly, for the next two weeks, Coastguard Beach is a dud for any real riding. The only glimmer is that Sunday, July 26th dawn glass – if you’re desperate for a clean, tiny wave, that’s your window. Otherwise, leave the board at home.

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.

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.
