The Lowdown

Alright, folks, Rusty here. Let’s cut to it: the next 16 days are a rough watch. We’ve got a long, flat spell starting from Friday the 4th all the way through to Saturday the 13th. Nine days of barely a bump. The swell is tiny, the period is short, and the wind is mostly cross or onshore, just ruining what little energy is there. It’s a proper lull.

Coastguard Beach is the only break in the game, and it’s a beginner-friendly, exposed beach that’s usually consistent. Not this time. The water temp is 68°F, which is about average for this time of year, so at least it’s not freezing. The wave energy is weak, mostly in the 20 to 38 range for the first week—nothing to write home about. The best you get is a brief moment on Monday afternoon the 7th when the wind goes glassy and the swell hits 3 ft from the ENE with a 10-second period. But it’s still called “very ordinary,” so that’s a one-session, nothing-special deal.

The one true standout, if you can call it that, is Thursday morning the 10th. We get a push of 4 ft swell from the SSW, with a moderate offshore wind from the WSW keeping it clean. The combined energy hits 159, which is moderate and gives it some punch. The period is 8 seconds, so it’s a short-period swell, but with offshore wind, it could offer a few decent waves for a patient surfer. The swell direction is a bit off the optimum SE, so it won’t be perfect, but it’s the best you’ll see all period.

After that, it’s a ghost town. From the 11th to the 19th, we’re looking at tiny waves, mostly under 2 ft, with weak energy and cross or onshore winds. There’s a glassy morning on Monday the 14th and another on Wednesday the 16th, but with only 0.6 ft to 3 ft on offer, it’s flat and frustrating. The combined energy stays under 100 for almost all of it. Honestly, if you’re a kite surfer, the strong cross-shore winds on Sunday the 6th and Friday the 11th might look better than anything a paddle surfer can do. For the rest of us, it’s a waiting game. Forecasts can change, and this spot is usually consistent, so don’t give up yet, but right now, there’s nothing to chase.

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.
