The Lowdown
Alright, Rusty here. Let’s talk about what’s lining up for us at Caspar Creek.
Honestly, mate, it’s a tough run ahead. We’ve got a long stretch of poor conditions with the wind constantly messing things up. For most of this period, the northerly winds are either cross-on or onshore, and that’s keeping the waves choppy and lumpy. The water temp is sitting at about 57° – that’s roughly 1° cooler than normal for this time of year, so pretty average really.
Thursday the 27th kicks it off with a tiny 2ft southwest swell, but the 15-second period means some energy in the water – the combined energy is moderate at 253. However, those cross-onshore winds make for poor surf. That trend continues right through the weekend. By Saturday the 29th, the swell bumps up to 6ft from the northwest, but the wind is up to 19 mph and it’s lumpy, so no good. The combined energy on Saturday afternoon hits 735, which is moderate, but with that wind, forget it.
Sunday the 30th sees a 7ft northwest swell, but again, cross-onshore wind. The combined energy is 504 – moderate – but the conditions remain poor. This pattern doesn’t let up. Through the end of August and into the first week of September, it’s the same story: building swells with periods around 7 or 8 seconds, and the wind is always cross-on or onshore. The combined energy values hover in the 200s to 800s, so there’s decent swell energy in the water, but the wind is a killer.
Now, there is a tiny window of hope. On Tuesday the 8th of September in the afternoon, we get a glassy moment. The swell is only 2ft from the southwest, but it’s a long-period groundswell of 18 seconds, and the combined energy is 381. They’re calling it surfable but ordinary – I’d say it’s a scrap for the patient. Then, on Wednesday the 9th of September in the afternoon, we see our best chance: a 3ft southwest swell with a 16-second period, combined energy of 459, and glassy conditions. That’s the standout. A clean, long-period swell that will need a reef or point to hold its shape, but if you can find a corner, it’ll be worth the wait. After that, Thursday the 10th and Friday the 11th see the wind shift back to cross-on, and the swells drop off, with combined energy falling back into the 100s.
So, to be honest, the only real glimmer in this 16-day window is that Wednesday the 9th of September afternoon. Everything else is a battle with the northerly wind. For beginners, the swell never really gets over 5ft in a clean state, so that’s not a factor, but the wind is the problem, not the size. This is a classic case of an area that’s pretty consistent in its shortcomings during this time of year. We just have to wait it out.
Rusty, signing off.

Information about the Caspar Creek Surf forecast
The above surf forecast table for Caspar Creek provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Caspar Creek can be found by selecting the local surf guide option on the grey menu. Our Caspar Creek 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 (Caspar Creek) 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 Caspar Creek 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.
