The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for Caspar Creek over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch. The water temp is sitting at 59°F, which is pretty much normal for this time of year, nothing wild there. But the surf? Man, it’s a long, dry spell. We’re looking at a solid 10-day gap of nothing but "poor surf conditions" from the 8th of September all the way through to the morning of the 18th. The wind is almost always a cross-on shore breeze, and the swell is mostly short-period, wind-driven junk. The wave energy is mostly moderate (229 to 1362), but it’s all messy, so it doesn’t matter.
The first real glimmer of hope isn’t until Friday the 18th of September. It’s not a world-beater, but it’s the best on offer. The Friday morning sees a shift to an onshore wind from the west at only 3 mph, which is the closest we get to clean. The swell is a small 2 ft from the SW, but it’s got a long 19-second period, so there’s some quality groundswell energy in the water (418). The break is a sheltered spot, so that long-period SW groundswell should wrap in decently. The combined energy is moderate (418). It’s a beginner-friendly break and consistent, so if you’re just starting out or want a longboard crusier, this is your window. The only downside is that it’s a "marginal" call, so don’t expect perfection.
The rest of the extended forecast into the 23rd is more of the same story: small, short-period swells with cross-onshore winds. The wind state finally cleans up enough to be "light" at times, but the swell is just too small and weak to get excited about. The Saturday the 19th and Sunday the 20th have some SW swell, but it’s barely 3 ft and the wind is still cross-on.
To be honest, there’s nothing here that’s going to get the heart pumping. If you’re desperate for a paddle, the Friday 18th morning is your only real shot. Otherwise, it’s a waiting game. Forecasts can change, and this spot is consistent, so it won’t be flat forever.
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.
