Autumn's Embrace: New Hampshire's Weather Forecast for October 18, 2025

As the vibrant hues of autumn continue to paint the New Hampshire landscape, Friday, October 18, 2025, is set to deliver a quintessential fall day, offering a delightful mix of conditions for residents and visitors alike. Our latest comprehensive weather video report from WMUR outlines what you need to know to make the most of your day, whether you're planning outdoor adventures or cozy indoor moments.

Starting off, many areas across the Granite State will awaken to a crisp, invigorating morning.

While skies might begin with a hint of cloud cover in some regions, particularly further south, expect them to gradually give way to generous spells of brilliant sunshine. This interplay of sun and cloud is characteristic of our New England autumns, providing that perfect backdrop for the season's spectacular display.

Temperatures will remain comfortably cool, reflecting the heart of autumn.

Most of the state can anticipate daytime highs reaching into the mid-50s (around 12-14°C). Overnight lows will dip significantly, settling into the upper 30s to low 40s (3-6°C), especially in the northern and higher elevation areas. So, if you're stepping out early or staying out late, a warm jacket or sweater will be your best companion.

However, the day isn't entirely without its nuances.

A weak disturbance is expected to brush through the region later in the afternoon and into the evening. This could bring with it the chance of isolated, scattered rain showers, particularly across the central and southern parts of the state. These showers are not anticipated to be widespread or heavy, rather quick passing drizzles or light rain.

It’s always wise to keep an umbrella handy, just in case!

Wind conditions will generally be light to moderate, predominantly from the northwest, ensuring that crisp, clean air quality we cherish this time of year. While gusts are not expected to be significant, they will add to the cool feel, especially in exposed areas.

For those eager to enjoy the legendary New Hampshire fall foliage, conditions remain near peak in many central and northern areas, while southern regions are showcasing vibrant colors.

The blend of sun and cool temperatures today provides an excellent opportunity for leaf-peeping, hiking, or simply enjoying a scenic drive.

Looking ahead into the weekend, the forecast suggests a gradual clearing trend and slightly warmer temperatures for Saturday, before another system moves in for Sunday.
