The Lowdown
Hey everyone, Rusty here. Let's get into the outlook for this stretch of coast at Caspar Creek.
First thing, the water's around 58°F, which is right where it should be for the season. The ocean's got some energy in it right now, reading a moderate 635 (combined energy of all swells directed here), but don't let that fool you.
The real story for the next week is the wind. Starting Sunday the 13th through Wednesday the 16th, we have a persistent NW cross-onshore breeze at 10 to 15 mph, sometimes stronger, that's just tearing up the surface. There's a solid 5 to 7 ft swell from the NW, but with that wind, it's all chop and whitewater. Not worth your time. That's a solid four days of rough conditions.
There's a slight shift Thursday the 17th afternoon, with the wind dropping to a light 3 mph onshore from the WSW, and the swell backs down to about 4 ft from the NW. It's a bit more manageable, but still not clean. Then Friday the 18th brings in a tiny 2 ft groundswell from the SW with a really long 19-second period and a light westerly onshore. The size is just too small to get excited about, even with the long-period shape.
The weekend of the 19th and 20th stays small, with that same long-period SW groundswell at 2 ft to 3 ft. Light onshore winds keep it weak and small.
Now, mark your calendar for Monday the 21st of September. A new NW swell arrives, jumping to 8 ft in the morning and hitting 10 ft by the afternoon. The period is short at 8 to 9 seconds, and the wind is a gentle cross-onshore from the NNW. The combined energy is a strong 1780 (combined energy of all swells directed here). This is a big step up in size. The best window across the whole 16 days looks to be Tuesday the 22nd of September morning, with an 8 ft NW swell and the wind just a light 6 mph onshore from the west-northwest. The energy is massive at 1965 (combined energy of all swells directed here). Tuesday afternoon sees the swell at 10 ft from the NW, and the wind goes very light from the southwest – that's the cleanest wave we'll see, but at that size, it's for experienced surfers only.
The rest of the run, from Wednesday the 23rd through to the 28th, delivers more NW swell, but the wind stays a problem. It's mostly cross-onshore from the SSW or NW, keeping the surf lumpy and messy. Thursday the 24th and Friday the 25th have moments with light winds, offering a small quality window, but the wind ruins it again soon after. The final days, the 27th and 28th, get hit by a fresh to strong 20-30 mph NW cross-onshore, making for truly horrible conditions. The standout, and really the only one worth chasing, is Tuesday the 22nd of September with that big NW swell and the lightest wind in the whole forecast.
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.
