The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' at Caspar Creek over the coming weeks. Fair warning, it's a bit of a mixed bag, and we're gonna have to be patient.
Gotta be straight with you – the next week and a half is pretty grim. The wind is almost always coming from the northwest, which lights up that cross-onshore wind and chops the surface to pieces. Sure, Saturday the 12th sees a clean 3ft swell from the southwest with a long 14-second period, and the wave energy is moderate (747), but that morning wind is a solid 12 mph onshore. It's not surfable in any pleasant way. Sunday the 13th and Monday the 14th just get bigger and chunkier, with the swell jumping to 10ft by Monday afternoon (strong wave energy at 1467), but the wind stays cross-onshore and strong. For a sheltered spot like Caspar Creek, that's just messy.
We finally get a little relief on Wednesday the 16th. The afternoon goes glassy, the swell is a solid 6ft at 8 seconds, and the energy is moderate (398). It's described as "surfable but very ordinary." That's the most hopeful thing we've seen so far. Thursday the 17th afternoon also goes glassy, with a smaller 4ft swell. It's a chance to get wet, but nothing to write home about.
Honestly, the standout window looks like it finally arrives over a week away, on Tuesday the 22nd of September. Tuesday morning the wind swings to a light 3 mph offshore from the west, and the swell is a meaty 7ft. But it's Tuesday afternoon that's got my heart pumping – glassy conditions, an 8ft swell from the northwest, 8-second period, and very strong wave energy (1361). The forecast says "expect very good surf conditions." For this spot, that's the real deal. The size is in the expert range, so it won't be for everyone, but if you've got the chops, that's your session.
Unfortunately, the run of poor surf continues right through the rest of the period after that, with the cross-onshore wind returning. So, the outlook is a long wait for that one Tuesday afternoon window. It's not all bad news though – the break is consistent, so when the stars align, it can fire. But for now, keep your board in the car and be ready to pounce on that Tuesday the 22nd.
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.
