The Lowdown
G’day, it’s Rusty. Let’s be straight with you—this 16-day stretch for the Caspar Creek area is a tough one to get excited about. The poor conditions start right away on Wednesday the 5th, with light cross-onshore wind and waves around 4ft from the NW, but it’s messy and not worth paddling out for. Honestly, the first week is a write-off. The swell builds through Saturday the 8th, jumping to 8ft in the afternoon, and by Sunday the 9th we’re looking at 10ft from the NW with a moderate cross-onshore breeze. That’s a lot of water moving, but it’s choppy and blown-out—more for the kite crowd than surfers. The period stays around 9 seconds, so there’s some push, but the wind is just trashing it.
The early part of the second week, Monday the 10th through Wednesday the 12th, keeps that 7ft to 10ft NW swell, but the cross-onshore wind doesn’t let up. The energy is strong, but it’s still marginal at best. By Thursday the 13th, the wind finally swings onshore from the W, and the swell drops to 5ft to 6ft. It’s still only a 1 or 2 out of 10, so nothing to rush out for. The period is a consistent 9 seconds, which helps, but the overall quality is just ordinary.
Now, here’s the one bright spot. Friday the 14th afternoon. The wind drops to a glassy 3 mph from the WNW, and we finally get some clean conditions. The swell is 5ft from the NW with a 9-second period, and it’s the best looking window of the whole run. The water temp is about average for this time of year, so no surprises there. Caspar Creek is a sheltered beginner-friendly spot, and while it’s consistent, it’s not a standout. But that Friday afternoon glass will have it looking tidy.
The last couple of days, Saturday the 15th and Sunday the 16th, drift back to light cross-onshore winds and 5ft to 6ft NW swell. Still nothing special. The period stays around 8 to 9 seconds, and the energy is moderate. We’re looking at a lot of “poor” and “marginal” labels through to the 20th. The long-range stuff—into the 18th and 19th—shows 7ft to 7ft NW swell but with the same cross-onshore issue, so it’s not worth banking on.
So, bottom line: the only real chance you’ve got is Friday the 14th afternoon when it goes glassy. It’s not big, it’s not epic, but it’s clean, and that’s the best we’re getting. The rest of the window is blown out or just average. Keep your expectations low, and if you can, wait for that Friday glass.
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.
