The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Caspar Creek. Gotta be straight with you – the first week-plus is a bit of a write-off. We’re staring down a long stretch of poor conditions right from Monday the 31st of August. The wind is all over the place, mostly onshore or cross-onshore, and the waves are just messy. You’ll see a bit of swell bumping around, but the quality is shot. This is one of those blank runs that feels like it’ll never end, but keep the faith – it’s just how this setup goes sometimes.
We finally get a glimmer of hope on Thursday the 10th of September. The morning is still a bit of a write-off, but come the afternoon, things get real interesting. The wind drops to glassy, and we’ve got a solid 7ft swell rolling in from the NW. The combined energy is pumping at 1182 (moderate to strong), and with that period around 9 seconds, it’s got some proper shape. This is the standout session of the whole outlook – clean, glassy waves at a spot that’s sheltered and consistent. It’s a beginner-friendly break, but with this size and those conditions, everyone’s gonna be smiling. The water temp is about average for this time of year, so no need to worry about a freak chill.
Hang on, because the real heavy stuff shows up later. Sunday the 13th of September is a beast. The afternoon goes completely glassy with a 12ft NW swell and a combined energy of 2178 (strong to very strong). Now, that’s expert territory – over 8ft – so don’t even think about it if you’re not solid. The period is 9 seconds, so it’s got power but not the super-long lines that’d make it tricky. This is the other big highlight, but only for the experienced crew. It’s a long-range call, so while it looks incredible, don’t book the trip just yet.
The days in between are all just big, bumpy NW swell with cross-onshore winds – not worth paddling out for. The 14th and 15th of September keep the size up, but the wind conditions are a mess. For the first few days, with the poor surf quality and onshore wind, this setup looks more interesting for kite surfing than paddle surfing.
So, to wrap it up: you’ve got a long wait, but Thursday the 10th afternoon is your best bet for clean, fun waves. And for the big-dog crew, Sunday the 13th afternoon is the one to watch.
Rusty.

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.
