The Lowdown
Alright folks, Rusty here. Let's get into it. We're looking at a pretty grim stretch ahead for the Caspar Creek area. The next 16 days are a total write-off, I'm sorry to say. The pattern is relentless: persistent cross-onshore winds, mostly from the NW, messing up anything that tries to form. The water temperature is sitting at 57°F, which is about 1°F cooler than usual for this time of year – nothing too crazy, just a bit nippy.
The first few days are a total bust. Wednesday, August 19th, we've got a 6 ft NW swell but with a short 8-second period and a cross-onshore breeze, it's just a choppy mess. The combined energy is moderate at 517, but it's all for nothing. Thursday and Friday are smaller, around 3 ft to 3 ft, with a longer period but still plagued by that cross-onshore wind. The energy drops into the 200-300 range. Saturday, August 22nd, starts tiny with 2 ft and then jumps to a short-period 5 ft in the afternoon with a stronger breeze – still no good.
Sunday the 23rd brings a bit more size, 6 ft to 6 ft, and the energy climbs back over 500, but it's still cross-onshore. The Sunday afternoon slot gets a marginal score of 1/10, but that's the best we'll see for a while. The wind stays terrible all through the next week. Monday the 24th through Friday the 28th, we're looking at 5 ft to 8 ft of NW swell, but the wind is always cross-onshore, and the period is short, between 6 and 9 seconds. The energy is moderate to strong, hitting 1025 on the 29th, but it's all blown out.
The last few days of August and into September are more of the same. Saturday, August 30th, has an 8 ft NW swell, which is getting big and will only be for experts, but it's still a cross-onshore mess with a 30 km/h breeze on the 31st. The first week of September is a bit smaller, around 5 ft to 6 ft, and the wind stays onshore or cross-onshore. Finally, on Thursday, September 3rd, we get a tiny 4 ft WNW swell with a longer 11-second period and a marginal score of 1/10 in the afternoon, but it's still cross-onshore.
Honestly, there's nothing to recommend. The wind is the enemy here, and it doesn't let up. For a beginner spot, the conditions are just too messy. The setup looks more interesting for a kite session than a paddle session, if you're into that. It's a tough run, but Caspar Creek can be a bit like this. The forecasts can change, but for now, keep your gear dry.
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.
