The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Caspar Creek over the next couple of weeks.
Right off the bat, we’re in a bit of a dry spell. The first few days are just not happening – Friday the 17th through Sunday the 19th is a write-off with messy cross-onshore winds and dodgy surf. You’re better off staying on the couch. The real glimmer in this forecast comes on Monday morning, the 20th of July. That’s the standout window. We’ve got a 5ft swell rolling in from the NW with glassy conditions – a light breeze from the WNW at just 3 mph. The combined wave energy is moderate (479) and the period is short at 8 seconds, so it’ll be a bit lumpy and quick, but with that glassy surface it’ll be worth the paddle. Caspar Creek is a sheltered beginner spot that’s consistent, so this is a good one for the learners and anyone wanting a clean, easy session. The water temp is about average for this time of year, nothing unusual.
After that Monday morning, it’s back to the grind. Tuesday the 21st offers a glimmer Tuesday afternoon with glassy 3ft waves from the NW, but it’s weak energy (173) and very ordinary. From Wednesday the 22nd right through to the end of July, it’s a long stretch of poor surf – mostly cross-onshore winds, low energy, and choppy conditions. The swell does pick up again around the 28th and 29th of July, with waves hitting 5ft to 7ft, but the wind is straight cross-onshore and the surf is poor. That’s more of a kite-surfing setup than a paddle session.
Then on Saturday the 1st of August, we get a late surge: 8ft from the NW with moderate combined energy (1238) and a 9-second period. But the wind is still a cross-onshore breeze at 9 mph, which kills the quality. For experts only, and even then it’s marginal.
So here’s the bottom line: if you’re surfing Caspar Creek, the one true window is Monday morning, July 20th. Get it while it’s glassy. The rest of the forecast is a long, frustrating gap with nothing to write home about. Stay patient – forecasts can change, but right now it’s a waiting game.
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.
