The Lowdown
Alright folks, Rusty here. Let’s break it down for Caspar Creek. Water temp is about 58°F, pretty normal for the season, so no surprises.
The first real chance to surf kicks off Monday, August 10th. The swell is pushing 10ft out of the NW, but the wind is a cross-on from the NW at 9 mph. It’s a mess – the energy is strong (2303), but the quality is poor. The period is a short 9 seconds, so the waves are just lumpy. The morning might be just barely rideable, but the afternoon is a bust. If you’re new, 10ft is too big, so stay on the beach.
Tuesday the 11th is the same story. The swell stays big at 8-10ft, with the same cross-on wind. The energy is high (901-1238), but it’s choppy. Not worth it.
Now, Wednesday the 12th gets interesting. The wind goes offshore from the WNW at 3 mph in the morning. The swell drops to 8ft from the NW, with a 9-second period. Energy is still solid (1089), and the wind is finally good. The wave is still big for most, but for the experienced guys, this is the first real window. The afternoon gets a cross-on from the SW, so the morning is your shot.
Thursday the 13th is the real standout. The morning is okay, but the afternoon… the wind goes glassy at 3 mph from the west. The swell is a clean 7ft from the NW, with a 9-second period, and the energy is moderate (654). The forecast says “good surf conditions,” and for this spot, that’s gold. The water is still 58°F. This is the best day of the 16. The wave will be clean and a solid size for a point break. Thursday afternoon is the one.
After that, it fades. Friday the 14th drops to 4-5ft with poor, choppy conditions. The weekend of the 15th and 16th is tiny – 2ft to 3ft with weak energy (22-119). The swell just dies. There’s a gap of poor to no surf from Friday the 14th through Tuesday the 18th.
Then, on Wednesday the 19th, a new pulse arrives. The swell is 4-5ft from the WNW, with a very long 13-second period. Energy is high (1128-1371), but the wind is a cross-on from the NW. The long period will have some power, but the beach break might be too straight. The morning is marginal, the afternoon is poor. It’s a tease.
The rest of the window into the 22nd is a mix of weak, short-period windswell and cross-onshore winds. Nothing to get excited about.
So, the clear winner is Thursday, August 13th in the afternoon. Glassy conditions, 7ft NW swell, and a clean wave. If you can only go once, make it that day.
Rusty, signing off.

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.
