The Lowdown
Alright, Rusty here, with a look at what’s coming up for Jacks Hole.
Right off the bat, I gotta be straight with you – this is one of those quiet spells where the ocean just isn't cooperating. We're looking at a long, frustrating stretch of tiny surf and poor conditions that runs from now, Monday the 17th of August, all the way through to the 25th. For over a week, there’s just nothing worth paddling out for. The swell is flat, the energy is weak, and the forecast is full of “poor surf conditions” comments. It’s a tough run.
The first sign of life doesn't show up until Wednesday the 26th of August. Wednesday morning, we see a bump in the swell – 4ft from the SSE with a short 4-second period. The combined wave energy is still weak at 49, but the wind is a light cross-off from the NNW, which should keep things clean. It's not a standout by any stretch, but it's the best we've seen in a week. Wednesday afternoon sees the energy pick up to 132 (moderate), with a 3ft SSE swell and a slightly longer 7-second period. The NNW wind stays cross-off, so the surface should be smooth.
Now, the water temp here is a real talking point – it’s sitting at 65°F, which is 4°F warmer than normal for this time of year. That's notably warm, and you might not even need a full spring suit for those weak little waves.
The rest of the outlook into late August and early September stays stubbornly small. We see some 2ft S swells on the 28th and 29th with clean conditions, but the energy is low and the period is short. Nothing really builds into anything solid. Thursday the 27th is practically flat again.
Honestly, for a break that needs a decent south swell and offshore west winds to really work, this 16-day window is a dud. The only real window to maybe get wet for a grovel session is Wednesday the 26th. Don't expect any barrels or power – it'll be small, clean, and probably a bit frustrating. Jacks Hole is a fairly consistent spot, so this kind of flat run is just part of the deal sometimes. Forecasts can always change, but right now, it's a waiting game.
Rusty.

Information about the Jacks Hole Surf forecast
The above surf forecast table for Jacks Hole provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jacks Hole can be found by selecting the local surf guide option on the grey menu. Our Jacks Hole 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 (Jacks Hole) 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 Jacks Hole 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.
