The Lowdown

Alright folks, Rusty here. Let’s get straight into what’s on offer.

Honestly, looking at the full 16 days, it’s a pretty bleak stretch for Coastguard Beach. We’ve got a long, quiet run ahead with very little to get excited about. The first record we see is for Sunday, August 2nd, and it’s a weak 2ft southerly swell with a short, choppy 4 second period. The combined energy is a measly 16, and with a cross-shore wind, it’s just poor surf. That sets the tone.

The only real bump in the road comes on Monday, August 3rd, during the morning. We get a 6ft swell from the south, but the period is still a short, weak 6 seconds. The combined energy jumps up to 262 (moderate), and the wind is a clean cross-offshore from the SSW at 28 mph. That’s a strong breeze, but it will keep the surface clean. The swell is over 5ft, so it’s starting to push into territory that’s not ideal for beginners. Still, for a brief window, it’s the most size you’ll see.

After that, it’s a long, slow death. From Monday afternoon onward, the swell drops back to tiny 0.3ft to 3ft, with periods mostly under 9 seconds. The combined energy almost never climbs above 60, and most of the time it’s below 30. The wind is often clean, but there’s simply no energy behind it. The forecast is consistent, but consistently poor. There’s a gap of many days here with no real surf on offer, just weak, background slop.

The only standout, if you can call it that, is that Monday morning window on August 3rd. It’s a 6ft south swell with clean winds, making it the best of a very bad bunch. Even then, the short period means it won’t have much shape. For a beginner, it’s probably too much, and for an expert, it’s not enough. The set-up is a beach break, and with the wind coming from the SSW, it’s a cross-offshore, which should help with the line-up.

Water temp at the start is 67°, which is about average for the time of year, with the anomaly sitting at -1°.

If you’re a kite surfer, the strong, clean wind on Monday morning might be more interesting than the waves for paddling. For the rest of the month, it’s a quiet, flat spell that’s pretty normal for the area. Forecasts can change, but right now, there’s not much 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.
