Late August in Vermont is shaping up to feel more like early fall than the tail end of summer. A stretch of cooler-than-normal temperatures is expected to hold steady across the state through Labor Day weekend and into early September. While the summer heat has backed off, the chill in the air might catch some off guard — especially those planning outdoor celebrations.
Cooler Air Settles Over Vermont
The National Weather Service in Burlington reports that Vermont is likely to stay below average in temperature from August 27 through at least September 5. This is due to a large upper-level trough across the eastern and central U.S., which is pulling cool Canadian air southward.
The highest chances for cooler weather fall between August 27–31, with areas like the Champlain Valley, northeastern Vermont, and towns such as Montpelier, Rutland, and St. Albans expected to feel the greatest chill.
Here’s what to expect:
Daytime highs a few degrees below the seasonal average
Nighttime lows potentially dipping into the upper 40s in higher elevations
Crisp mornings and cool evenings, especially in rural and elevated areas
Impact on Labor Day Plans
With Labor Day weekend approaching, many Vermonters may be planning barbecues, picnics, or outdoor trips. While there’s no major storm system in sight, the cooler weather means you’ll want to dress in layers, especially if you’re heading out in the morning or staying out after sunset.
Tips for Labor Day Events in Cool Weather:
Carry a light jacket or hoodie, even during the day
Use outdoor heaters or fire pits for evening gatherings
Consider moving events indoors or to covered patios if temperatures dip too low
Keep blankets handy for kids or elderly guests who feel the cold more
Could This Affect Local Agriculture?
While the weather isn’t cold enough to bring frost, it could slow down late-season crops or delay some final planting. Gardeners and farmers should monitor soil temperatures and check upcoming forecasts before scheduling any major planting activities.
The growing season warmth is gradually fading, and this cool spell could signal the beginning of a more sustained shift toward early autumn conditions.
Looking Ahead to September
Long-range forecasts suggest that below-normal temperatures will likely continue into the first week of September. However, updated guidance will be issued in the coming days, giving a clearer picture of whether the chill will persist or if a brief warm-up is possible after Labor Day.
Vermont is heading into a cooler stretch just as summer winds down. With temperatures likely to stay below normal through Labor Day weekend, now’s the time to bring out the light sweaters and enjoy the crisp, clean air. While the cool-down is a welcome break from the summer heat, it’s also a reminder that fall is just around the corner.
