The Lowdown
Alright, folks, let's break down Caspar Creek. I'm not gonna sugarcoat it – this is a tough run.
Water temp is around 57°, which is a touch below normal for the season, but that's the least of our problems. The main issue is a persistent cross-onshore wind that's been wrecking what little swell we get.
From Thursday, August 27th, through the end of the month, it's all poor surf. The wind is constantly blowing from the northwest, making everything choppy. On Saturday, August 29th, we've got a 2.5m northwest swell, but with a 19 mph cross-onshore wind, it's just lumpy and unrideable. The swell energy is moderate at 756, but it's all for nothing.
The first week of September doesn't improve much. Monday, September 1st, has a tiny 0.9m northwest swell with light wind, but the energy is weak at 63 and the conditions are poor. The only real glimmer of hope is on Tuesday, September 8th. That afternoon, the wind shifts to a light southerly cross-offshore, and the swell is a clean 1.6m from the northwest. The energy is moderate at 500, and the conditions are described as "clean." That's your one and only window.
After that, it's back to poor surf, with a big 3.5m northwest swell on Friday, September 11th, but it's choppy and messy with a 12 mph cross-onshore wind. That's expert territory, and even then, the wind ruins it.
So, the verdict is grim. The only surfable session in the entire 16-day window is that Tuesday afternoon, September 8th. If you're a die-hard, that's your shot. Otherwise, this setup looks more interesting for kite surfing than paddle surfing. It's a rough patch, but it won't last forever.

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.
