The Lowdown
Alright, surfers, Rusty here. Let’s be honest, looking at this stretch ahead, it’s a bit of a rough patch. We’ve got a period of groundswell building, but the wind is going to be a constant thorn in our side. Most of this outlook is going to be about finding the least messy option, not the perfect wave.
To start, the first real chance of anything surfable will be on Saturday, August 10th. Before that, it’s a washout. The swell will be there, but it’s junky and wind-blown. The water temp is sitting right where it should be for this time of year, about 58°F, so nothing unusual there. The whole window is dominated by a NW swell, which is fine, but it's the cross-onshore wind that's going to make things ugly.
The real issue is that the wind is forecast to be cross-on from the northwest almost constantly. This is a problem. For example, on Sunday, August 11th, we have a decent 8ft to 10ft swell with a solid 9-second period, and the energy is cranking, hitting 1984 in the morning. But with a moderate cross-onshore breeze, it’s going to be a choppy mess. Not worth the paddle.
The window from August 12th through the 14th sees the swell ease slightly but the wind stays stubborn. It's not until the afternoon of Tuesday, August 13th, that we get a break in the action. The wind drops to a glassy 3 mph, and the swell is still a solid 6ft from the NW with a 10-second period. The energy reading is a moderate 614. This is our first real standout. Caspar Creek is the break, and with the wind going glassy, it’s going to be the cleanest it’s been all week. It’s a consistent spot, but it can get crowded, so get out there early.
After that tease, the swell backs right off. The surf drops into the 3ft range, and we slide into a stretch of flat, weak days from August 15th through the 18th. The energy readings are weak, dropping below 100, and the waves are not worth a look. This is a solid four-day stretch where you can leave the boards in the shed.
Things get interesting again on the 19th. The swell is still small, only 4ft, but the period jumps to a very long 12 seconds. This is a long-period groundswell. The energy gets a boost, too, hitting a strong 690. But here’s the catch. That long period, combined with Caspar Creek’s beach-and-reef setup, can make it break a bit too straight. Plus, that northwest wind comes back with a vengeance, hitting 16 mph in the afternoon. It’s a promise of clean energy, but the ocean is going to be a mess. It’s a frustrating one.
The final days are more of the same - the swell stays small, around 3ft, and the wind is still onshore. It’s a poor end to a tough run. There’s one last pulse on the 21st with a 13-second period, but the 12 mph winds will keep it from being anything you’d want to paddle into. All things considered, if you’re going to get wet, that Tuesday afternoon on the 13th is your only real shot.
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.
