Traveller notes on Burlington in May
Notes from nearby Stowe (42 km away)
Burlington doesn't have its own notes for May yet — these are about Stowe, close enough to share the season.
Stowe-forum threads on a May visit call this genuinely mud season locally, posters describing conditions capable of staying muddy right through the month depending on how the winter and spring went. Regulars call hiking trails on state land, including the Long Trail and its feeder routes, typically closed from early April through Memorial Day. Posters recommend the Stowe recreation path and the Lamoille Valley Rail Trail as real alternatives, both open to walkers and cyclists regardless of the mud closures elsewhere. Regulars call real black flies a standing nuisance near running water, a genuine annoyance though harmless. Posters describe May as still genuinely rewarding for birding and wildflowers, orioles and various spring ephemerals real highlights for anyone working around trail closures. Regulars recommend checking current trail status before planning any higher route. The record: 19.7C days feeling like 18C, 5.2C nights, 102.4mm across over 11 days and 72 percent humidity.
Other months in Burlington
Forum posters describe December in Burlington as cold, gray and dreary with short days, typical daytime highs in the 30sF and lows in the teens to 20sF, and posters note a relatively low chance of snow specifically in early-to-mid December compared to deeper winter. Posters are consistent that the city stays lively despite the weather, describing downtown Church Street as festively lit for Christmas with restaurants, bars and live music keeping the atmosphere upbeat through the cold, quiet season. Posters flag that real winter sports - skiing, snowshoeing and similar activities - require transportation out of town rather than being available within Burlington itself. Posters generally rate December as a quiet, atmospheric time to visit Burlington for anyone not chasing snow sports specifically.
Forum posters describe early June as warm but genuinely variable - one visitor logged a range from the 60s up to the high 80s F within the same trip, and a light rain jacket gets recommended for the spring-showers chance that lingers into the month. June is called a quieter window since the colleges have emptied out for summer, ahead of the bigger July-August crowds. Leddy Park comes up repeatedly as the go-to for warm-weather activities - swimming, fishing, or just hanging out on the bike path and beach - alongside the festivals and outdoor concerts that start filling the streets as the season turns.
