The Lowdown
Alright folks, Rusty here. Let’s have a look at what Bethany has in store for us over the next couple of weeks. Straight up, I gotta be honest with you—this is a grim outlook. We’re looking at a long stretch of pretty ordinary conditions, so don't get your hopes up.
The water temp is sitting at a balmy 76°F, which is a massive 4°F warmer than usual for this time of year. That’s very unusual and means you might not even need a spring suit, but unfortunately, the surf quality just isn't matching the warm water.
For the first week, from Monday the 14th right through to Saturday the 19th, it’s basically a write-off. We’ve got tiny swell, poor surf conditions, and cross-onshore winds messing things up. There’s a brief moment on Thursday morning the 17th where the wind goes light and cross-offshore, making it clean, but the swell is a pathetic 2 ft from the east with only a moderate combined energy of (62). It’s surfable, but barely. You’d be scratching for anything rideable.
Sunday the 20th gives us a tiny glimpse of hope. The morning stays clean with a light cross-offshore breeze, but again, the swell is just 1 ft. The real highlight, if you can call it that, is Sunday afternoon. The wind goes glassy, and with a 1 ft ESE groundswell at 11 seconds, you might find a few knee-high sliders if you’re desperate. The energy is a weak (26). It’s not good, but it’s the best we’ve got in this first stretch.
Then we hit a big change. From Monday the 21st through Wednesday the 23rd, the swell picks up significantly, but it’s accompanied by strong onshore winds. Monday afternoon sees 6 ft from the ENE, with combined energy hitting (347), but it’s choppy and messy. Tuesday the 22nd morning is the biggest of the period, with 7 ft from the east and strong energy (583), but with a 25 mph cross-onshore, it’s a complete washing machine. This is strictly for experts only, and even then, it’s not going to be pretty. By Wednesday afternoon the wind swings cross-offshore, cleaning it up, but with 5 ft from the east and fresh winds, it’s still a tough paddle for average surfers. The setup looks more interesting for kite surfing than paddle surfing on those days.
The final few days, from Thursday the 24th to Tuesday the 29th, see the swell drop back down. Thursday morning the 24th is the only other moment worth a mention. We get 3 ft from the east with a light offshore wind from the WSW. The combined energy is a modest (170), and it’s clean. It’s surfable, but very ordinary. After that, it’s back to small, weak, and mostly choppy conditions through the end of the month.
So, to be blunt, there are no standouts here. If I had to pick the absolute best of a bad bunch, I’d say Sunday afternoon the 20th for the glassy conditions on a tiny groundswell, or Thursday morning the 24th for a slightly bigger, cleaner wave. But don’t expect much. It’s a tough run for Bethany, and sometimes that’s just how it goes. Forecasts can change, but for now, leave the boards in the car and enjoy the warm water from the beach.
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.
