The Lowdown
Alright, Rusty here. Let me tell you straight up, looking at this 16-day window for Coastguard Beach, it's a tough stretch. This is going to be a long, quiet period for us. The honest truth is none of the days are shaping up to be a proper session, so don't get your hopes up for a standout. The whole forecast is a dud.
We start off this Friday, July 17th, with barely a ripple – 0.3ft of weak easterly energy, and a cross-onshore wind making things messy. That flat, choppy theme carries right through the weekend and into the start of next week. We see the swell bumping up just a touch around Tuesday the 21st and Wednesday the 22nd, but it's still small, poor quality stuff. Wednesday morning is the most energetic we get all week, with that southeast swell reaching 3ft and a period of 9 seconds, giving us moderate combined energy of 233. The wind is clean, coming cross-offshore, so it will be glassy, but honestly, for a spot that needs more push, it's just not enough to get excited about. It's a 'could-have-been' kind of day.
After that midweek tease, it flat-lines again. We're looking at a massive gap from Thursday the 23rd evening all the way through to the end of the period on August 1st with nothing but tiny, weak surf and poor conditions. The water is sitting at about 68°F, which is pretty average for around here this time of year, but you won't need a wetsuit for these ankle-biters.
So, here’s the bad news: there isn't a single day I’d recommend paddling out at Coastguard Beach in this forecast. The swell is just too weak and the wind is working against us most of the time. It’s a real bummer, but sometimes the ocean just shuts down like this. For a beginner spot that is usually consistent, this is a rare blank run. Don't bother waxing up, just wait for the next system.
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.
