The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us.

Honestly, it’s a tough start. We’re looking at Coastguard Beach, and for the first week and a half it’s pretty grim. The swell is tiny and the wind is all over the place. There’s a bit of a pulse building around Wednesday the 22nd, with a waist-high S swell showing up, but the wind is still messy. The combined energy hits 398 (moderate wave energy) by Wednesday afternoon, but the forecast still calls it poor surf conditions. That’s a shame.

The first real standout doesn’t appear until Thursday morning, July 23rd. We’ve got a solid 4ft swell from the SSE, with a period of 10 seconds. The wind is a clean cross-off from the NW, which means the face will be nice and clean. The combined energy is 256 (moderate wave energy) – it’s got some push. The water temp is about average for the time of year at 67°. This is about as good as it gets in this window for a standard surfer: manageable size, clean conditions. It’s a consistent spot, so you should get plenty of waves, but crowds are possible here.

Now, if you’re an expert looking for a bit more punch, cast your eyes to Tuesday, July 28th. The morning brings a 5ft swell from the S with a short period of 7 seconds. The wind is a strong cross-off from the WNW, keeping it clean. The combined energy is 221 (moderate wave energy). This is bigger, but with that short period it’s going to be a bit dumpy and more for the experienced crew. It’s a consistent spot, so you’ll get waves, but be ready for the power.

After that, the swell fades fast. We go into a flat spell from around July 31st right through to the second week, with nothing rideable. It’s a long gap of about four or five days with no real recommendations.

Then, on Monday, August 3rd, there’s a flicker of hope. The morning shows a 4ft swell from the S, with a light offshore wind from the WSW. The combined energy is 164 (moderate wave energy). The report says “surfable waves but very ordinary conditions,” so don’t expect a classic. The period is a short 8 seconds, so it’ll be a bit soft. It’s a long-range call, so keep your expectations in check.

Best bet of the whole run? That Thursday morning, July 23rd, at Coastguard Beach. Clean, chest-high, and a bit of energy. Get it while you can.

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.
