The Lowdown
Alright folks, Rusty here. Let’s get straight into it. Honestly, looking at the next 16 days, it’s a bit of a tough stretch for Caspar Creek. The pattern is pretty consistent: we’ve got cross-onshore winds from the Northwest for the vast majority of the forecast period, which is going to keep things choppy and messy. There’s not a single standout morning or afternoon where the wind cleans up and gives us that glassy, offshore magic we crave. The swell is coming in from the Northwest, matching the direction this spot prefers, but the wind is just ruining the party.
We start off on Saturday, August 15th, with a small 3ft NW swell, but it’s pretty weak at only 7 seconds and a combined energy of 98. By Sunday, the 16th, it’s a similar story with 3ft. The water temp is about average for the time of year, nothing unusual there. The combined swell energy is low, under 100, so the waves just don’t have any punch. The real problem is that cross-onshore breeze. It’s light, but it’s enough to put a ruffle on the surface.
As we move into the middle of the week (Monday the 17th to Wednesday the 19th), the swell picks up a bit, hitting 4ft to 6ft. The combined energy gets into the moderate range, hitting 580 on Wednesday morning, so there’s some power behind it. But again, the wind is a constant cross-onshore from the NW, and the period is short (6-7 seconds), so the waves are just going to be lumpy and uninviting. Thursday the 20th gives us a brief tease with a 3ft swell from the WNW, but it’s got a 12-second period, which is a nice long groundswell. The combined energy is still moderate at 420, but it’s still cross-on, so you’re not getting the clean face you’d hope for with that period.
The second week really ramps up in size. From Saturday, August 22nd, through to the end of the month, we’re seeing solid swell numbers: 5ft, then 7ft, 8ft, up to 13ft on Friday, August 28th. The combined energy goes from moderate to very strong, hitting 2159 on that Friday. This is expert-level territory for sure, especially when it’s over 8ft. But the wind never lets up. It’s still cross-onshore from the NW, making it a washing machine. With that much size and cross-on wind at a beach break, this setup honestly looks more interesting for kite surfing than paddle surfing. The period stays short, mostly 8-9 seconds, which means it’s going to be a close-out mess.
The only real hint of something better is on Sunday, August 23rd, and Monday, August 24th, mornings. The winds drop to a light breeze, and the swell is 7ft to 7ft from the NW. The combined energy is strong (586 and 780), and the comment says “marginal surf forecast.” It’s not perfect, but it’s the closest we get to a clean window. If you’re desperate, paddle out early those mornings, but crowds are likely at Caspar Creek, so don’t expect a quiet session. For the rest of the run, it’s a no-go. The gap of truly poor conditions stretches from the start all the way to the end.
Overall, there’s no true standout in this 16-day window. The size is there for the experts in the second week, but the wind kills it. For the rest of us, it’s a blank run, which is a bit of a bummer, but these stretches happen here. Forecasts can change, so keep an eye on it.
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.
