As of today, September 20, hikers in the New Hampshire 4000 Footers will encounter varied conditions across the trails. Currently, many areas are experiencing rain, with temperatures hovering in the low 30s to mid-40s, and winds generally ranging from 5 to 20 mph. Expect mud and wet rock sections, especially in lower elevations, while higher peaks may have patchy fog and reduced visibility due to moisture in the air. Water crossings may be swollen from recent rains, so be prepared for slippery conditions underfoot. Looking ahead, the weather is set to improve starting Monday, with temperatures dropping into the 20s at night and daytime highs only reaching the low 40s. The forecast shows a transition to mostly sunny skies by mid-week, which will aid in drying out some trails, but be aware of the potential for freezing temperatures at night leading to frost and ice formation, especially on higher summits. This freeze/thaw cycle can create tricky footing in the mornings, so timing your hikes to avoid the coldest parts of the day will be crucial. Hikers should come equipped with layers to accommodate the chilly temperatures and wind, along with waterproof jackets to stay dry. Traction devices like microspikes may be necessary, especially on steeper trails and during the morning hours when ice is likely to form. It’s advisable to avoid routes that are particularly prone to fast-moving water crossings or those that are known for slick rock, as conditions may remain treacherous for a couple of days post-rain. Always be cautious and prepared for changing weather, especially in the higher elevations where conditions can shift rapidly.
