The Lowdown
Alright folks, Rusty here. Let’s get real about this stretch at Caspar Creek. I’ve been staring at the charts and, honestly, it’s a tough read. The whole 16-day window is looking pretty grim for a decent paddle. We’ve got a long stretch coming up with nothing really worth getting wet for, so don’t hold your breath.
The trouble starts now and it’s a long wait. The first few days are a write-off. Thursday and Friday the 16th and 17th are a mess – cross-onshore winds and short-period junk are making a mess of things. The water temp is sitting at 55°, which is actually about 1° cooler than normal for this time of year, so it’s a bit nippy for a lake swim, let alone surfing.
We’re looking at a gap of about 6 days before we even see a glimmer of hope. The only thing that catches my eye is the Monday afternoon of the 20th of July. Swell is small, coming in from the SW at 3 ft, but the period is a solid 16 seconds, which is proper groundswell. The wind is forecast to be glassy. That’s the only window we’ve got. It’s a tiny, clean wave, but it’s the one standout in a sea of mediocrity. The combined energy is moderate (673), so it’s not a pump fest, but it’ll be a fun little wave for a log or a mid-length.
After that, it’s back to the same story. From Tuesday the 21st right through to the end of the month, it’s a non-stop parade of cross-onshore slop, building winds, and messy conditions. By the end of July and into the 31st, the swell actually gets big – up to 12 ft on the 26th – but it’s short-period windswell with a howling cross-breeze. That’s not surfable, it’s a washing machine. If you’ve got a kite, it might be interesting, but for a paddle surfer, it’s a hard pass.
So, the bottom line: this is a 16-day forecast with one, maybe two, hours of hope. The 20th of July is your shot. Keep your eyes on the forecast, because it tends not to stay this poor for long, but right now, Rusty is saying stay home, wax the board, and wait.

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.
