The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, straight up, this is a pretty grim stretch for Coastguard Beach. We’re looking at a solid 16-day window, but the first ten days or so are a write-off for any decent paddle surfing. The swell is tiny, the wind is messy, and most of the time the conditions are just plain poor. You’ll see a few days where the energy picks up a bit, but the wind direction and strength just ruin any chance of a clean wave.
The first real glimmer of anything surfable doesn’t pop up until the morning of Wednesday, July 22nd. The swell bumps up to 5ft from the south, and the wind is a cross-off, which is a big positive. The combined energy of all swells directed here hits 340 (moderate wave energy), so there’s some push. The period is a short 8 seconds, so it’s windswell, not super clean, but it’s rideable. The afternoon sees the swell rise to 6ft from the south, with energy hitting 505 (strong wave energy), and still cross-off wind. For a bigger, stronger surfer, this could be the best of a bad bunch, but it’s still only rated as marginal. The water temp is sitting at 67°F, which is about normal for this time of year, so no need to worry about a major thermocline.
The next spot that might get your attention is the afternoon of Wednesday, July 29th. The swell is a weak 3ft from the ENE, but the real story here is the wind. It’s glassy. That’s a rare treat. The combined energy is 112 (moderate wave energy) and the period is a short 6 seconds, so the waves will be small and a bit choppy, but with zero wind, you might get a few clean, fun little rollers. It’s not a standout, but it’s the only time the ocean looks like it’s cooperating.
So, to sum it up: if you’re a beginner, ignore everything until the very end of the month. The 6ft swell on the 22nd might be a bit much for you. For the rest of us, plan for Wednesday, July 22nd if you have a bigger board and want some punch, or Wednesday, July 29th for a tiny, glassy session. The second week is a total bust, with nothing but small, onshore slop. It’s a tough run, but forecasts can change, so don’t write the whole month off.
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.
