The Lowdown
Alright, Rusty again. I’m looking at the same charts but in feet and miles per hour. It’s a tough run for the whole region. The only spot worth talking about is Jacks Hole, a reef break for advanced surfers, fairly exposed to the south, and it likes a south swell. The water is 64°, which is a touch warmer than normal for this time of year.
The first week and a half is a real snooze. From Wednesday morning the 12th all the way to the end of the week on the 22nd, the swell is tiny—fractions of a foot—with periods all over the place and combined energy barely hitting double digits. We get a few clean windows, like Friday morning the 14th with a light NNW cross-off, but there’s nothing to surf.
Finally, on Friday the 21st, the morning brings a 3ft swell from the north, but it’s a short 5-second period. The wind is a gentle cross-shore from the NNE, and the combined energy is 58. It’s weak, but it’s the first real bump.
The best swell of the whole run hits on Sunday the 23rd. The afternoon has a 4ft swell from the SSE, with a 5-second period. The wind is a light cross-on from the ESE, and the combined energy is 81. It’s short-period, so it’s going to be a bit lumpy, but it’s the biggest we’ve got.
The cleanest session is Monday the 24th. The morning has a light cross-off from the NW with a 2ft swell from the SSE, and the afternoon goes glassy with a NE breeze and a 2ft swell. The combined energy is 42 in the morning and 25 in the afternoon. That glassy afternoon is a real beauty for a reef break.
After that, it’s back to tiny, clean but weak surf for the rest of the run. The 25th and 26th are clean but tiny, and the period drops to 7 seconds on the 27th.
So, if you’re looking for a window, make it the afternoon of Monday the 24th. That glassy, clean afternoon at Jacks Hole with a little SSE swell is your best bet. It’s small, but it’s clean, and for a reef, that’s the ticket.
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.
