The Lowdown
Alright, let’s get into it.
First off, the big picture for this stretch of coast is pretty grim for the next week and a half. We’ve got a lot of junky, short-period swell and near-constant cross-onshore winds messing things up. For a beach that’s as exposed as Nesika Beach, that combination is a recipe for close-outs and chop. If you’re jonesing for a wave, you’re going to have to be patient.
The 17th and 18th are blown out. We're looking at a moderate breeze from the NNW, cross-onshore, and lumpy conditions. There’s some swell on the way, but it’s not organized and the wind makes it a mess. The combined energy is moderate at best. It’s a write-off for surfing.
That run of poor conditions stretches all the way through the 24th. We see some glimmers of hope on the 20th, with lighter winds and a bit bigger WNW swell, but the wave comment still says poor. The 21st is marginal, but honestly, at around 2ft and light winds, it’s a gamble. The winds stay cross-onshore through the weekend and into the early part of the next week. We’ve got building, short-period NW windswell—the kind that just walls up and closes out. The energy is moderate to strong, but the quality is just not there. It’s more of a kite-surfing kind of day than a surfing day.
But here’s the light at the end of the tunnel. The morning of Tuesday the 25th is looking like a real standout. We’ve got a glassy, slight air with light westerly winds. The swell is tiny—only about 2ft—but it’s from the SW with a long 17-second period. That’s proper groundswell energy. It’s going to be clean and lined up. This is your window. Grab a longboard and make the most of the glass.
The next real window is on Tuesday the 1st of September. Tuesday afternoon shows another glassy period, with light WNW winds and a 2ft SW swell with a 14-second period. The energy has built a bit, so there might be a little more push to it. This is another promising, clean session.
Between the 26th and the 1st, it’s back to the NNW winds and cross-onshore slop. We even see a strong breeze with gusts to 25 mph on the 30th and 31st, making it properly messy. The swell directions are all over the place, and the wave comments are consistently poor.
So, to sum it up: the next week and a half is a write-off. Do something else with your time. But the 25th and the 1st of September are the standouts—clean, glassy, and with a touch of long-period groundswell. They’re small, but they’ll be the best waves on offer.
Remember, the water here is running much colder than normal for the time of year, sitting at 51 degrees Fahrenheit. That's a good 6 degrees below average, so you’ll want a proper hood and gloves.
Be patient, be ready, and be on it when the windows open.

Information about the Nesika Beach Surf forecast
The above surf forecast table for Nesika Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nesika Beach can be found by selecting the local surf guide option on the grey menu. Our Nesika Beach 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 (Nesika Beach) 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 Nesika Beach 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.
Nesika Beach is 90 km (56 miles) from Grants Pass. If you plan a vacation in South Oregon, look for hotels and other accommodation in Grants Pass. Grants Pass has rooms for a wide range of budgets as well as car hire and transport links.
