The Lowdown
Right, let’s have a look at what’s cooking in the water for the next couple of weeks.
Honestly, mate, this is a tough stretch. We’re looking at a long, barren run for Caspar Creek. The first recommendation doesn’t pop up until the morning of Sunday, 16 August, and even then, it’s not exactly a classic. The forecast is pretty grim for the first week, with persistent cross-onshore winds and very poor conditions. The swell is there, but it’s messy and uninviting. The energy levels are moderate for a lot of that period, like the morning of 9 August showing combined energy of 757, but it’s all chop and no shape. Don’t even bother paddling out until we get to that Sunday.
Sunday, 16 August morning is the first real glimmer, and it’s a small one. We’ve got glassy conditions with the wind dropping to calm, and the water temperature is sitting at 58°, which is pretty normal for this time of year. The swell is tiny, only 2ft, coming from the southwest with a very long period of 13 seconds. That’s a long-period groundswell, which can mean better shaped waves, but at a beach break like Caspar Creek, that long period can make it break too straight. The combined energy is weak at 131. It’s surfable, but you’ll be scratching for a ride. The crowds at Caspar Creek are often there, so don’t expect solitude.
The next week is more of the same story. The wind is mostly cross-on, and the conditions are poor or marginal. The water stays cold, and the swell is small and inconsistent. There’s a bit of a bump on the morning of Monday, 24 August, with a swell of 8ft from the northwest, period 9 seconds, and a cross-on wind. That’s a big wave for Caspar Creek, well over 8ft, so it’s strictly for experts. The combined energy is massive at 2086, but the wind is cross-on, so it’s going to be a challenging, messy beast. It’s a marginal call, and more than a week away, so treat it as a promising but uncertain prospect.
All in all, if you’re dying for a paddle, the glassy 2ft Sunday morning is your only real chance for a clean wave. The rest is a write-off. For a spot like this, it’s a normal run of quiet days. The setups look more interesting for kite surfing than paddle surfing for most of the period.

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.
