Hollis has a way of tricking you. You wake up thinking it's a standard New England morning, only to find the thermometer doing gymnastics. If you’re checking the weather Hollis New Hampshire today, January 15, 2026, you're looking at a high of 47°F with partly sunny skies. Sounds decent, right? Well, don't leave your heavy coat at the office. By tonight, that number is going to plummet to a bone-chilling 16°F.
That's a 31-degree swing in a single day.
Honestly, that’s just life here. People talk about "four seasons," but in Hollis, you often get three of them in a 48-hour window. Right now, we're sitting at 38°F with light rain and an 88% humidity level that makes the air feel heavy and damp. The wind is barely a whisper at 2 mph from the east, but that’s the calm before a much colder front moves in tomorrow.
The January Reality Check
January is technically the coldest month in town, with historical averages usually hovering around a high of 32°F and lows of 16°F. But look at the next few days—it's a mess.
Tomorrow, Friday the 16th, the sun comes out, but the temperature dies. We're looking at a high of only 28°F and a low of 16°F. Oh, and the wind picks up to 15 mph from the west. That’s going to bite. If you’re planning on being outdoors, Friday is the day you’ll regret skipping the thermal layers.
What's Coming This Weekend?
- Saturday (Jan 17): Expect snow. There’s a 65% chance during the day with a high of 34°F. It’s not a blizzard, but it’ll be enough to make the roads slick.
- Sunday (Jan 18): Light snow continues with a high of 33°F.
- Early Next Week: It gets even colder. By Tuesday, January 20, we’re looking at a high of only 20°F and a low of 8°F.
Basically, the "January thaw" we’re seeing today is a total lie. It’s a brief window of 47-degree warmth before the Arctic air "returns with a vengeance," as the local forecasters like to say.
Why Hollis Weather is Different from Nashua or Manchester
You'd think being so close to Nashua would mean the weather is identical. It’s not. Hollis has a higher elevation (about 370ft) and all those rolling orchards and open fields create micro-climates.
The "Hollis Frost" is a real thing. Because of the way cold air settles in the valleys near the fruit orchards, like Brookdale or Lull Farm, temperatures can be 5 degrees lower than what you see on your car's dashboard in downtown Nashua. This matters immensely if you’re a gardener or just someone trying to figure out if your pipes are going to freeze.
Seasonal Survival: A Local's Guide
If you’re moving here or just visiting, you’ve gotta understand the precipitation cycles. May is actually our wettest month, with a 38% chance of rain on any given day. September is the driest.
Winter (December - March): It’s freezing. Period. January is the peak for snow, averaging about 13.3 inches. You’ll see plenty of "Clippers" moving through, which are fast-moving systems that drop a few inches of powder and then vanish.
Spring (April - May): This is "Mud Season." The average high in April is 55°F, but the ground is a sponge. This is also when the maple sugaring happens, which requires those specific freezing nights and thawing days.

Summer (June - August): July is the hottest, hitting highs of 83°F. It gets muggy. The humidity in July can make an 80-degree day feel like a swamp.
Fall (September - October): This is the "Goldilocks" zone. Highs in the 60s and 70s, crisp air, and perfect for the town's famous apple picking. October is actually the month with the most rainfall (about 3.9 inches), which keeps the foliage colors deep and vibrant.
Dealing with the Extremes
We’ve had some wild hits over the years. Remember the 2008 ice storm? Or more recently, the "Bomb Cyclone" events that seem to happen every other year now. In fact, since 1980, New Hampshire has seen 21 weather disasters that cost over a billion dollars. Most of those were winter storms.
When a Nor’easter hits Hollis, it’s not just the snow; it’s the wind. On Friday, we’re expecting 15 mph winds, but during a real storm, those gusts can easily top 50 mph, knocking out power across the wooded backroads of Silver Lake Road or Depot Road.
Actionable Tips for Hollis Residents
- Watch the Dew Point: In the summer, don't just look at the temp. If the dew point is over 65, stay inside or hit the lake.
- The "Two-Layer" Rule: Between October and April, never leave the house without a base layer and a windproof shell. The 47-degree high today is a trap.
- Monitor Local Stations: Don't just rely on national apps. Local stations like KNHHOLLI97 (the Hollis Station) give much more accurate readings for our specific elevation than a general "Nashua area" forecast.
- Prep for Tuesday: With a projected low of 8°F on January 20, now is the time to make sure your snowblower has fresh fuel and your salt buckets are full.
Check your heating fuel levels today while the weather is still "mild" at 38°F. Once those 8-degree nights hit next week, delivery trucks will be backed up for days.
Next Steps:
- Clear your gutters today before the light rain turns into ice tonight.
- Set your programmable thermostat to account for the 31-degree drop coming over the next 12 hours.
- Prepare for Saturday's snow by ensuring your vehicle's tires are properly inflated for the colder, denser air.
