The Lowdown
Alright, let’s look at this same stretch in feet and knots.
Right, so here’s the deal: the first week or so at Caspar Creek is pretty rough. We’ve got cross-onshore winds and lumpy, choppy conditions from Sunday the 13th through to the middle of the next week. There’s swell, but it’s not clean. You’re looking at 7ft on Monday morning with moderate energy (830) and 10ft on Monday afternoon with strong energy (1493), but that cross-onshore wind is messing it up. Anything over about 5ft is getting big for beginners, and once you’re over 8ft, that’s expert-only, but with that wind, it’s just not fun.
There’s a quiet patch around the 17th and 18th with tiny 2ft swell and long periods up to 19 seconds—groundswell but tiny and still cross-onshore. Water temp is about 58°, nothing special.
The bright spot? Thursday the 24th of September. We’ve got a morning with glassy wind, barely a breath, and a 5ft NW swell with moderate energy (650) and an 11-second period. Glassy conditions mean clean, smooth waves. Caspar Creek is sheltered and consistent, so it’ll hold that swell nicely. That Thursday morning is the one to aim for. The afternoon drops to 4ft, still glassy but smaller. After that, the wind turns back to cross-onshore for the rest of the 16 days, so you’ve got a narrow window.
Looking further out, Monday the 28th has some bigger swell—7ft NW at 13 seconds, with strong energy (1937)—but it’s cross-onshore again in the afternoon, so it’s a maybe. Don’t count on it.
Overall, this run is mostly a bust for clean surfing. The standout is that Thursday the 24th morning at Caspar Creek. It’s not huge, but it’s clean, and that’s all we’ve got.

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.
