The Lowdown
Alright, folks, Rusty here. Let's talk about what's doing at Caspar Creek for the next couple of weeks.
Honestly, it's a rough stretch. We've got a 16-day window, and there's not a single session that I'd be excited to paddle out for. The first wave worth mentioning is on Sunday the 23rd of August, but it's a tough one.
Sunday morning, we've got a small 0.6m swell from the SW with a long period of 19 seconds. That's a groundswell, and the combined energy is 456 (moderate), but the wind is cross-onshore from the NW at 15 km/h, making it choppy. Water temp is 13°, which is a bit colder than usual for this time of year. The wave report says it all: poor surf conditions. Sunday afternoon has a 1.8m NW swell, but the period is a short 7 seconds and the wind is still cross-onshore. It's marginal at best.
From Monday the 24th through the end of August, it's a real bummer. The swell stays small, 0.6m to 2.5m, but it's all from the NW or SW with short periods, mostly 6 to 8 seconds. The wind is consistently cross-onshore from the NW, 10 to 35 km/h, keeping things choppy and lumpy. The combined energy gets up to 854 (strong) on Friday the 28th afternoon, but with that short period and cross-onshore wind, it's just a messy, blown-out mess. None of these are worth your time. The wave comments are all "poor surf conditions" or "marginal."
There's a big gap at the start of the month. Tuesday the 1st of September has tiny 0.4m and 0.5m swells with combined energy of only 34 and 26 (weak). It's basically flat and choppy. Wednesday the 2nd and Thursday the 3rd see a slight uptick, with 1.3m to 1.4m swells from the WNW, period 8 to 9 seconds, and combined energy in the moderate range. But the wind is still cross-onshore, and the waves are still poor. No standouts.
The only thing that gets close to interesting is late in the forecast. Friday the 4th of September afternoon has a 1.8m swell from the NW, period of 11 seconds, and combined energy of 771 (strong). The wind is still cross-onshore though, so it's choppy. Saturday the 5th of September afternoon sees a 3.0m swell from the NW, period 8 seconds, and combined energy of 1001 (very strong). That's a big wave for Caspar Creek, and at 3.0m, it's only for experts. It's way too big for beginners. But again, the wind is cross-onshore at 20 km/h, so it's not clean. It's choppy and messy. The setup is a beach break, and with that strong, short-period swell and onshore wind, it's looking more interesting for kite surfing than paddle surfing.
Caspar Creek is a sheltered spot and it's consistent, but the conditions just aren't lining up. The water temp is a bit colder than normal, and the wind is almost always a problem. There's no magic window here. The second week looks just as poor, with nothing changing. Don't waste your time.
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.
