The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Caspar Creek over the next couple of weeks.
Straight up, I gotta be honest with you – this isn't the best run we've seen. The whole first week is going to be a bit of a write-off. We’ve got a solid gap with no real surf to speak of from now until the end of the month. The wind is mostly cross-onshore, and the wave quality is just poor. You’ll see some small, weak swell around, but the combined energy is low, often in the 200-400 range (moderate), and it’s just not going to shape up. The period is all over the place, too, with that 16-second groundswell early on – that’s a long wait between sets, and it’s coming from the SW, which isn't ideal for this sheltered spot.
Things start to look a little more interesting for the first week of September. The morning of Thursday the 3rd has some swell building, but it’s still messy. The real standout, the one you want to circle on your calendar, is the morning of Friday the 4th of September. We get a glassy, offshore wind from the WSW at just 3 mph, and the combined energy is a solid 433 (moderate). The swell is 6ft from the NW, and with that glassy surface, the wave quality is expected to be good. That’s the session to go for. Keep in mind the water temperature is about 58°, which is pretty normal for this time of year, so a good wetsuit is a must.
Now, if you’re an experienced surfer, the morning of Tuesday the 8th of September is the big one. The forecast is showing a serious pulse of energy with a combined energy of 1533 (strong). We’re looking at a 10ft NW swell, and the wind is glassy from the NNW. This is huge, and it’s going to be heavy. The period is 9 seconds, so it’s a bit shorter-period groundswell, but with that much water moving, it’s going to be powerful. This is strictly for experts. The afternoon, however, the wind cranks up to 19 mph and the session is blown out, so get out there early.
The rest of the second week is a bit of a mixed bag. The swell stays up, but the wind is generally cross-onshore, keeping things choppy. The morning of the 9th still has some size, but the conditions won't be clean. The best bet, and the only true standout, is that glassy morning on the 4th of September.
Stay safe, and I'll see you in the water.
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.
