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. I’ll be straight with you – it’s a pretty quiet start, but there’s a flicker of hope later on.
Right now, and for most of the next week, the conditions are a bit of a letdown. The swell is there, but it’s mostly cross-onshore, choppy, and the wave quality is just poor. We’re looking at a long stretch of days where the surf just isn’t cooperating. From Tuesday, August 25th, all the way through to the end of the month, the wind is coming from the NW and NNW, blowing across the waves and ruining the face. The swell heights do bump up a bit around the 29th and 30th, with some 5ft to 7ft NW swell, but the energy is moderate (around 226 to 468), and that cross-wind makes it messy. Honestly, it’s just not worth paddling out for.
We hit a bit of a lull after that. The first few days of September are small, with weak energy readings dropping to just 24, and still that cross-on wind. It’s a real struggle.
Then, things start to look interesting. The first real standout pops up on Thursday, September 3rd. The morning has some clouds and a light WSW wind turning onshore, but by the afternoon, the wind goes glassy – dead calm from the SW. The swell is 4ft from the WNW with a period of 9 seconds, a moderate energy of 299. It’s not huge, but with that glassy surface, it’ll be clean and smooth. This is the first time we see something worth a look.
The next gem is on Saturday, September 5th. The afternoon session is the one to target. The wind goes glassy again from the WSW, and the swell is building to 6ft from the NW, period of 8 seconds, and a solid moderate energy of 407. The conditions are described as “expect good surf conditions,” and that’s the kind of talk I like to hear. This is shaping up to be the best day on offer for the whole outlook.
The following day, Sunday, September 6th, has a similar setup. The afternoon is glassy again, with the swell reaching 7ft to 8ft from the NW. The energy is strong here, hitting 746 and 800. That’s a lot of power. With a period of 8-9 seconds, it’s a bit short, but the energy is there. Just be aware that at 8ft, this is pushing into expert territory; it’s going to be a handful for beginners.
The water temperature is sitting at 58°, with an anomaly of -0.9°, so it’s pretty average for the time of year down at Caspar Creek. The break itself is a sheltered, consistent beginner spot, and it breaks often, so it’s usually not a total zoo, but it can get crowded sometimes. The optimum swell direction is from the NW, and the better swells we see later on are from that direction, which is a good match.
So, to wrap it up: the first week is a write-off. A long gap of poor conditions. The real action starts on Thursday, September 3rd afternoon, with Saturday, September 5th afternoon being the standout. The glassy winds and building NW swell will make it worth the wait. The following Sunday also has potential, but it’s bigger and more powerful, so pick your spot wisely.
Rusty out.

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.
