You’re standing on the boardwalk, coffee in hand, watching the sunrise paint the Atlantic in shades of neon orange. It’s 7:14 AM on a Friday in mid-January. The air is crisp—honestly, it’s cold—clinging to a steady 40°F. But if you’re looking at the Bethany Beach weather hourly stats, you’ve probably noticed that the "feels like" temperature is a much more aggressive 30°F.
That 10-degree gap is the coastal tax. It’s the result of a 18 mph wind whipping in from the south, a common occurrence that can turn a pleasant morning stroll into a test of endurance for your heaviest parka.
People think beach towns just go to sleep in the winter. They don’t. But the weather here is a fickle beast that requires more than just checking a daily high and low if you actually want to enjoy your time outside.
The Hourly Reality of Coastal Transitions
Most visitors make the mistake of looking at the daily high—today, it’s 40°F—and assuming they’re good to go. Big mistake. By the time the sun starts its descent, which is happening early these days around 5:03 PM, the temperature is going to plummet toward a low of 25°F.
If you’re planning an evening walk past the Totem Pole or toward the quiet end of Atlantic Avenue, you’re looking at a serious shift. The wind direction is slated to shift from the south to the west by the afternoon, picking up speed to about 20 mph.
This isn't just "breezy." It’s the kind of wind that cuts through layers.
Actually, the humidity is sitting at a comfortable 50% right now, which is a rare dry spell for Bethany. Usually, this place is a humidity magnet. In the summer, that moisture makes 85°F feel like 95°F. In the winter, it can make the cold feel "wet," deep-seated and impossible to shake off.
Why the Ocean Changes Everything
You’ve got to understand how the water dictates the Bethany Beach weather hourly flow. Even in January, the ocean acts as a giant thermal battery. It’s slower to cool down than the land, and slower to warm up.
Tonight, the sky is staying clear, which sounds nice until you realize that means there’s no cloud cover to trap the day’s heat. Heat just escapes into the atmosphere. The UV index is currently 0—basically non-existent—so don’t expect the sun to provide much warmth even if the sky looks like a perfect blue marble.
- Current Temperature: 40°F
- Wind: 18 mph South
- Precipitation Chance: 0% (Clear Skies)
- Humidity: 50%
Tomorrow, Saturday the 17th, things get a bit weirder. While today is sunny, tomorrow is going to be "much warmer," potentially hitting 49°F. But there’s a catch. The clouds are moving in, and by late Saturday night, we're looking at an 80% chance of rain.
Basically, if you want the dry, clear air, today is your window. Tomorrow is for indoor activities and watching the gray Atlantic from behind a window.

Surviving the Bethany "Microclimates"
It’s funny how a three-block walk changes the weather here. On the boardwalk, the wind is raw. Move two blocks west toward the salt ponds or the Assawoman Canal, and suddenly the wind drops. The houses and the slight change in elevation act as a shield.
If you're tracking the weather hourly for a run or a bike ride, always check the wind direction. A 20 mph wind from the west means you’ll have a brutal headwind heading back toward the water but a lovely "push" on your way out toward Route 1.
Honestly, the best resource for real-time tracking isn't a national app. It’s the town’s own weather stations located at Town Hall and the Boardwalk. They capture the immediate impact of the surf that bigger models sometimes smooth over.
Actionable Tips for Navigating Today’s Forecast
Don't let the "Clear" status fool you into under-dressing. Here is how to actually handle the next 12 hours in Bethany:
- Layer for the Wind, Not the Temp: A windbreaker over a fleece is more effective today than a thick wool coat that lets air through the knit.
- Watch the 4 PM Drop: As soon as the sun dips behind the buildings, the temperature will fall faster than you expect. If you’re out, head back by 4:30 PM.
- Check the Tides: If you're walking the beach, high tide can push you up into the soft, difficult sand near the dunes. With the current west-southwest winds, the surf might look deceptively calm, but the pull is still there.
The clear skies will hold through the night with 0% chance of rain, so if you're a fan of stargazing, the lack of light pollution combined with the dry air makes for a killer view of the constellations over the ocean. Just make sure you've got the 25°F low in mind before you set up a chair on the sand.
