The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Bethany.
Right off the bat, I gotta be straight with you – the surf is pretty damn quiet for nearly two weeks. There’s a big ol’ gap of nothing good, with just small, messy, or onshore junk. We’re not really looking at anything worth paddling out for until late in the run. The first real glimmer of hope doesn’t show up until Thursday the 24th of September, so you’ve got about 10 days of waiting before things finally turn on.
Let’s be honest, the first week and a half is a write-off. We’ve got tiny windswell, howling onshores, and a lot of “poor surf conditions” in the data. You’d be better off doing yard work. The water temp is sitting at 77°, which is way warmer than normal for this time of year – feels more like summer than early autumn, but it doesn’t matter much when there’s no waves to play in.
The big story, and the only real standout, hits on Thursday the 24th. That morning we finally get a bit of luck. The wind drops out completely – glassy conditions. The swell comes up to a solid 7 ft out of the east-northeast (ENE), with moderate energy (530). It’s a bit on the bigger side, so beginners might want to sit this one out, but for everyone else, it’s the cleanest we’ve seen. The glassy surface is a major win.
The afternoon of Thursday the 24th steps it up even more. Swell builds to 8 ft from the east (E), and the energy jumps to 1138 – that’s moderate to strong energy. The wind is a light cross-offshore from the south-southeast (SSE), keeping it clean. This is excellent for experienced surfers, with plenty of power.
Now, Friday the 25th is a beast, but it’s a bit of a double-edged sword. The morning shows a 10 ft east swell with a period of 10 seconds and massive energy (1954). The wind is light and cross-offshore – perfect conditions. But here’s the kicker: at 10 ft, this is getting serious. It’s definitely too big for most, and it’s a beach/jetty setup, so big east swells can close out or get shifty. The afternoon stays at 10 ft with an 11-second period and energy hitting 2023. This is for experts only. The water will be heavy. If you’ve got the skills and the board, it could be a session to remember, but it’s not a day for the faint-hearted.
After that, the wind shifts back onshore on Saturday the 26th and the quality drops off again, so that Thursday and Friday are your golden window.
The bottom line: if you’ve got patience, Bethany delivers a couple of cracking days right at the tail end of the forecast. The glassy Thursday morning and the big, clean Friday are the ones to circle. Everything before that is a skunk.
Rusty.

Information about the Bethany Surf forecast
The above surf forecast table for Bethany provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bethany can be found by selecting the local surf guide option on the grey menu. Our Bethany 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 (Bethany) 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 Bethany 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.
Bethany is 20 km (12 miles) from Ocean City. If you plan a vacation in Delaware, look for hotels and other accommodation in Ocean City. Ocean City has rooms for a wide range of budgets as well as car hire and transport links.
