If you’ve ever spent a week in Lancaster County, you know the local joke: if you don’t like the weather, just wait five minutes. Honestly, it’s not even a joke most of the time. Weather in Elizabethtown Pennsylvania is a wild ride of four very distinct, very loud seasons that refuse to be ignored. You get the humid, sticky afternoons of July where the air feels like a warm wet blanket, and then you’re scraping an inch of ice off your windshield in January while the wind whips off the surrounding farmland.
It’s a humid continental climate, or a "Dfa" if you’re into the technical Koppen classification. Basically, that means we get the best and worst of everything.
The Reality of Winter in E-town
January is, without a doubt, the toughest month here. Highs average around 37°F, but that doesn't tell the whole story. The "real feel" often drops into the teens because Elizabethtown sits in a bit of a gap where the wind likes to pick up speed across the fields.
Snow isn't always a given, but when it hits, it hits. You'll see an average of about 20 to 30 inches of snow over the season. However, we also deal with "wintry mixes"—that annoying slush that isn't quite snow and isn't quite rain. It makes Route 230 a mess.
One thing most people don't realize? February is actually the driest month. You’d think it’d be the wettest because of the snow, but the air gets so cold and brittle that it just doesn't hold much moisture. If you’re planning a move here, invest in a high-quality ice scraper and a humidifier for your house. Your skin will thank you.
Spring: The Mud and the Bloom
Spring in Elizabethtown is a bit of a tease. March starts out looking like winter's ugly sibling—lots of brown grass and gray skies. But then April hits.
Temperature-wise, you’re looking at a jump from the 50s in March to the mid-60s in April. This is when the Susquehanna Valley starts to wake up. It’s arguably the most beautiful time of year, especially with the local orchards starting to bud.
- The Rain Factor: May is technically our wettest month. You'll see about a 39% chance of rain on any given day.
- The Swing: It’s not uncommon to see a 70-degree day followed by a frost warning the next night.
- The Gear: Layers. You need a light jacket in the morning and a t-shirt by 2:00 PM.
Why Summer Humidity is the Real Story
If you’re coming from out west, the summer weather in Elizabethtown Pennsylvania might catch you off guard. It’s not just the heat; it’s the humidity. July is the peak. Highs average around 84°F, but with the humidity, it frequently feels like 95°F.
The humidity stays high—around 64% even in the "driest" part of the day. It’s that "heavy air" feeling.
Pop-up thunderstorms are a staple of E-town summers. They usually roll in around 4:00 PM after a day of building heat. They’re fast, loud, and usually drop a massive amount of rain in twenty minutes before the sun comes back out. These storms are actually responsible for most of our summer rainfall.

Severe Weather Risks
We don't get many tornadoes, but we do get "straight-line winds." Every couple of years, a storm will come through with 60 mph gusts that knock down old maple trees and take out power lines for a day or two. If the National Weather Service in State College issues a warning for Lancaster County, take it seriously.
Fall is the Local Favorite
Ask anyone who lives here, and they'll tell you: September and October are the reason we stay.
The humidity finally breaks in mid-September. The air gets crisp. September is actually the clearest month of the year, with sunny or partly cloudy skies about 65% of the time. It’s perfect for the Elizabethtown Fair or just walking around the Elizabethtown College campus.
Temperatures slide from the high 70s down to the low 60s by late October. The foliage is world-class. Because E-town is surrounded by diverse hardwood forests, the colors aren't just yellow; you get deep purples, oranges, and fiery reds.
A Month-by-Month Snapshot
To give you a better idea of what to pack, here’s how the year usually breaks down in prose:
January and February are the "stay inside" months. Highs are in the 30s, lows in the 20s. Expect wind and gray skies.
March and April are the transition. You'll see the first 60-degree days, but also the most wind. March is actually the windiest month, averaging over 13 mph.
May and June are the sweet spot before the real heat. Highs move from 72°F to 80°F. Everything is green, but keep an eye out for those May rain showers.
July and August are for the pool. It's hot, it's muggy, and the sun stays out for about 14 to 15 hours a day.
September and October are peak "hoodie weather." The humidity vanishes and the skies stay clear.
November and December see the return of the cold. Highs drop back into the 40s. November is actually the driest month for total liquid precipitation, though it feels damp because of the cooling air.

Dealing With the "Micro-Climates"
Because Elizabethtown is located in the "Piedmont" region of PA, our weather is slightly different than Harrisburg to the west or Lancaster city to the east. We’re high enough to get slightly more wind than the deeper valleys, but low enough that we don't get the massive snow piles they see up in the mountains towards State College.
One thing people get wrong is the "Lake Effect." We don't really get it here. By the time those storms cross the Allegheny Mountains, they’ve lost their "lake" moisture. Our big snows usually come from "Nor'easters" coming up the coast, though we’re far enough inland that we usually get the "back side" of the storm.
Actionable Insights for Residents and Visitors
- For Gardeners: Your hardiness zone is 6b. Don't put your tomatoes in the ground before Mother's Day. I know it’s tempting when we get a warm week in April, but a late frost in early May is almost a tradition here.
- For Homeowners: Check your gutters in late November. The heavy leaf fall combined with the December rains can cause basement flooding if your drainage isn't clear.
- For Visitors: If you’re visiting in July, stay somewhere with central air. Window units struggle with the PA humidity. If you're coming in October, book early—the "leaf peepers" fill up the local inns fast.
- For Drivers: Keep a small bag of sand or kitty litter in your trunk starting in December. The back roads around E-town can get icy fast, and the salt trucks take a while to get to the secondary routes.
The weather in Elizabethtown Pennsylvania is predictable only in its unpredictability. It demands a bit of preparation, but the reward is getting to experience four genuine, beautiful changes of scenery every single year.
Next Steps for Your Weather Prep:
- Check the local 7-day forecast specifically for the 17022 zip code, as Lancaster city forecasts can be 3-5 degrees off from E-town.
- Sign up for Lancaster County emergency weather alerts to get notified of flash floods or high wind warnings.
- If you’re planning an outdoor event, always have a "Plan B" indoor location for any date between May and August due to the high frequency of afternoon thunderstorms.
