New Hampshire Gears Up: A Detailed Look at Mid-October's Chilly Embrace and Shifting Skies

As New Hampshire moves further into October, residents are advised to brace for a distinct shift in weather patterns. The forecast for October 17, 2025, indicates a quintessential autumn day, characterized by crisp temperatures, the potential for scattered precipitation, and brisk winds that will make the fall foliage dance.

Starting the day, expect morning temperatures across the Granite State to hover in the low to mid-40s Fahrenheit.

While this offers a refreshing start, it's a clear signal to layer up, especially for those venturing out early. Coastal areas might experience slightly milder conditions, but the inland and mountainous regions will certainly feel the chill.

Throughout the day, high temperatures are projected to reach only into the low to mid-50s for most areas.

Don't be surprised if some northern peaks struggle to break into the 40s. The sky will likely present a mixed bag, with a blend of partly cloudy and mostly cloudy conditions. There's a noticeable chance for scattered rain showers, particularly in the afternoon and evening. These showers are expected to be light, but an umbrella or rain jacket will be a prudent accessory.

There's even a slight possibility of a rain-snow mix in the highest elevations as colder air descends.

Wind will be a significant factor, with gusts potentially reaching 15-25 mph, making the already cool air feel even colder. These blustery conditions could also lead to some leaf peeping challenges, so secure any loose outdoor items.

Visibility should remain good, but wet roads could become slick during periods of precipitation, especially as dusk approaches and temperatures begin to drop once more.

Looking ahead, this mid-October pattern is indicative of the transition into deeper autumn. Overnight lows after the 17th are expected to dip into the 30s, bringing the first widespread frost advisory for many regions.

Preparing homes and gardens for colder temperatures is highly recommended. Stay tuned to local weather updates from WMUR for any sudden changes or severe weather alerts as this dynamic season unfolds across New Hampshire.
