The Lowdown
Hey, it’s Rusty. Lookin’ at this 16-day stretch for Jacks Hole, I gotta level with you—it’s a grind. Don’t get stoked too early. Most of it is flat or nearly flat, with a long stretch of nothing worthwhile. The first couple weeks are tiny, weak swells and windy, messy conditions. Swell energy’s mostly between 4 and 71 (weak to moderate), with heaps of days at just 0.3ft to 2ft. Wind’s cross or onshore most times, so it’s choppy. Late in the run, there’s a little tease.
The one real highlight? Saturday morning, August 5th. After weeks of flatness and zero surf, we finally see a 4ft SSE swell with a 5-second period, and it’s glassy. Combined energy’s at 83 (moderate). That’s the standout, and pretty much the only one. It’s clean and small, but that short period and southerly direction might make the reef a bit tricky. Still, if you’re itching to get wet, that’s your time—think longboard or funboard. Before that, from August 21st right through September 4th, it’s a brutal dry spell: tiny waves, poor conditions, and scores that are basically zero. It’s a tough slog.
For Jacks Hole itself, it’s a reef break for advanced surfers, and crowds can show up sometimes. That glassy morning on the 5th is clean, but the swell’s small—exposed to the south, so it’s one for the locals who know the spot. Given the lack of size and some longer period swells (16 seconds) earlier that just didn’t deliver, this reef is your best bet.
Bottom line: Save your energy for early September. The rest is a washout. Water temp’s about average for this time of year—nothing special. This kind of blank run is pretty normal for the area in this season. Rusty out.

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.
