The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got cooking for the next couple of weeks at Caspar Creek. The vibe for this break is a bit of a rough one, honestly. It’s a sheltered little spot, so it needs a very specific key to unlock it, and the ocean just isn’t handing over those keys this time around.
We’re looking at a pretty bleak stretch starting off. The real kicker is that for the entire first week and more, the sea state is just not cooperating. We’ve got a bit of swell at the start—Monday the 10th sees a 8 ft NW swell with a short, weak 8-second period. The wave energy is moderate at 728, but the wind is a light cross-onshore, so it’s bumpy. It’s a poor surf picture. The water is sitting at 56°, which is a bit colder than usual for this time of year.
The next few days, from the 11th right through to the 20th of August, are a real write-off. There are no standout sessions. We see some 8 ft swell on the 12th with a combined energy jumping to 1627, which suggests some power, but it’s paired with a short 8-second period and a gentle cross-onshore wind that chops it all up—that wave is too fat and messy for real fun. For any beginner, that 7 ft to 8 ft range is getting too big, and with the chop, it’s just ugly.
Then from around the 16th, the swell drops right off. It’s a long dry spell. For over a week, the swell height barely hits 3 ft, and often sits down around 1 ft to 2 ft. The energy drops into the weak 2-digit range (like 25 on the 17th morning). There’s simply not enough water moving to shape up a wave.
Even into the second week, things don’t spark back to life. We get a little bump on the 21st and 22nd with 5 ft to 5 ft NW swells, but the period is still short (7-8 seconds) and the wind is consistently cross-onshore or light onshore. The waves will be shifty and lack any real push.
The real outlier here is the very end of the forecast, around the 24th and 25th of August. We get a tiny swell—only 2 ft—but it’s from the SW with a remarkably long period of 17 to 18 seconds. That’s a true groundswell. The combined energy is still moderate (around 367-373), and the wind is a light breeze. However, because Caspar Creek is a sheltered NW spot, a low-energy, long-period SW swell won’t wrap in properly. It’ll just feel like a long, glassy lull on the surface.
Bottom line: Caspar Creek is on a blank run. This is one of those times where the area just isn’t receiving any love from the ocean. It’s a normal situation for a sheltered spot. Keep an eye on the charts, but for the next 16 days, you’re better off finding a different activity.
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.
