New Hampshire's Weekend Weather: From Sunshine to Soakers and Beyond

Good morning, New Hampshire! As we step into September 6, 2025, prepare for a captivating shift in our beloved state's weather. Today promises a delightful start to the weekend, but don't get too comfortable – a classic New England transition is on the horizon, bringing with it a mix of conditions that will keep us on our toes.

Friday, September 6th, unfolds with picturesque conditions across the Granite State.

Expect abundant sunshine gracing our skies, complemented by comfortable temperatures settling into the low to mid-70s. It's the perfect day to enjoy outdoor activities, whether you're planning a hike through the emerging autumn foliage or simply savoring a quiet moment in your backyard. A gentle breeze will add to the pleasantries, making it an ideal day to kick off your weekend.

However, hold onto your hats, as the tranquility won't last.

Saturday, September 7th, marks the beginning of a noticeable change. While the morning may start partly cloudy and mild, clouds will steadily gather throughout the day. By the afternoon and evening hours, we anticipate the arrival of scattered showers, particularly in western and central New Hampshire.

Temperatures will remain mild, hovering in the upper 60s to low 70s, but the increasing humidity will be a clear indicator of the approaching wet weather.

Sunday, September 8th, is shaping up to be the wettest day of the weekend. Widespread rain is expected to move across the entire state, at times falling steadily.

This will bring a significant drop in temperatures, with most areas struggling to reach the low to mid-60s. It’s a day best spent indoors, perhaps curled up with a good book or enjoying some cozy family time. Travelers should exercise caution on the roads, as conditions will be slick, and visibility may be reduced.

Looking ahead to early next week, the pattern continues to evolve.

Monday, September 9th, may see lingering showers in some areas, especially in southern New Hampshire, before conditions gradually begin to clear. More notably, a much cooler air mass will settle over the region. Daytime highs for Monday and Tuesday are forecast to dip into the upper 50s and low 60s, bringing a distinct crispness to the air that truly signals the arrival of autumn.

Overnight lows will be quite chilly, possibly reaching the upper 30s in higher elevations, so be prepared for some frost potential in secluded spots.

In summary, this weekend in New Hampshire is a tale of two halves: a beautiful Friday giving way to a progressively wetter and cooler Saturday and Sunday.

As we transition into next week, a refreshing wave of autumn air will solidify its presence. Stay tuned to WMUR for the latest updates and enjoy the ever-changing beauty of New Hampshire's September weather!
