Look, if you’ve lived in the Monadnock region for more than a week, you know the drill. You wake up, check the thermometer, and then immediately ignore it because the wind coming off the mountain has other plans.
Right now in Peterborough, it’s about 30°F outside. It feels more like 21°F though. That’s thanks to a west wind kicking at 11 mph. It’s mostly cloudy, and honestly, it feels like typical January—chilly, gray, and a little bit stubborn.
The Immediate Breakdown
Today, Thursday, January 15, we’re hitting a high of 42°F. That’s basically a heatwave for us. But don’t get too comfortable. Tonight it’s plummeting to 11°F. That’s a 31-degree drop. If you don't drain your garden hoses or double-check the chickens, you're gonna have a bad time.
Tomorrow, Friday, January 16, the sun finally decides to show up. It’ll be sunny with a high of 25°F. However, keep the shovel handy. By Friday night, there’s a 40% chance of snow, and it’s staying cold with a low of 11°F.

Why the Peterborough NH 10 Day Weather Forecast is Weird This Year
Usually, January in Peterborough averages a high of about 30°F. Seeing that 42°F today is a bit of an outlier, but it’s followed by that brutal 1°F low on Tuesday. That’s the Monadnock effect. We get these weird pockets of warmth before the Arctic air decides to remind us who’s boss.
The humidity is hovering around 52% right now, but on Saturday it’s going to spike to 86%. That’s that "wet cold" that gets into your bones. No amount of wool socks can fully save you from an 86% humidity day when it’s 32 degrees outside.
Dealing With the Wind
The wind is mostly coming from the west and southwest this week. Expect speeds between 6 mph and 17 mph. Tuesday will be the windiest day, so if you have loose patio furniture (why?) or trash cans, maybe tie 'em down.

What You Should Actually Do
Honestly, just prep for the ice. With the snow-to-clear-to-snow cycle we're seeing, the sidewalks are going to be a nightmare.
- Check your salt supply. You’ll need it by Saturday night.
- Watch the Tuesday low. A 1°F night is when pipes like to cause drama.
- Layer up for the wind. A 17 mph wind at 13 degrees is basically a "stay inside" warning.
The weather in Peterborough is always a gamble, but this 10-day stretch looks like a classic New Hampshire roller coaster. Enjoy the 40s while they last today, because the single digits are coming for us next week.
Stay warm, keep the woodstove stoked, and maybe check on your neighbors before Tuesday night hits.
