The Lowdown
Alright mates, Rusty here. Let’s talk Caspar Creek – sheltered, small, and a bit of a mixed bag over the next couple weeks. Most of the time it’s not worth the walk, but there’s a couple windows that’ll get the blood pumping if you time it right.
Starting Sunday the 13th, we’re looking at northwest wind blowing cross-onshore at 9 to 19 mph, turning a building swell from 4 ft up to 7 ft by Monday afternoon into lumpy, choppy junk. Combined wave energy peaks around 1549 on Monday arvo – plenty of water moving, but no quality. Water temp is about 58°, normal for the season.
Thursday the 17th lightens up a bit with a lighter breeze, but the swell is 5 ft from the NW with a short period – still messy. By Thursday afternoon we get a slight improvement: wind switches onshore but only 3 mph from the west, leaving the surface glassy. Swell is 4 ft, energy around 401 (moderate). It’s only marginal, but the cleanest we’ve seen so far.
The 18th and 19th bring a long-period SW groundswell (18-19 seconds), but it’s tiny – just 2 ft. Wind stays cross-onshore. There’s potential, but nothing breaking properly.
Now, here’s the one to circle: Tuesday afternoon the 22nd. Wind goes dead calm – glassy. Swell is 5 ft from the northwest, 8-second period – short, but the surface will be clean as a mirror. Energy is 800 (moderate). Crowds can be likely, but when it’s this clean at a sheltered spot, it’s worth it.
Then Wednesday the 23rd afternoon is the real heavy hitter: 8 ft from the NW with a 13-second groundswell, glassy calm, and energy at 1922 (strong). That’s serious size for Caspar Creek, and for experts only – anything over 8 ft is for the brave. The long period might make it a bit straight at the beach, but the power will be there. After Wednesday, it’s back to onshore chop.
So here’s the call: skip the early junk. Aim for Tuesday 22nd afternoon for the cleanest small waves. Wednesday 23rd afternoon is for the experienced crew looking for proper size. After that, it’s all downhill again.
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.
