What to Wear in Boston in May

May in Boston marks a delightful transition from spring chill to pleasant warmth, though the weather remains famously fickle. Expect average daytime temperatures to hover in the mid-60s°F (18-20°C), with evenings and mornings often dipping into the comfortable 40s-50s°F (7-13°C). While you might encounter some gloriously sunny days pushing into the low 70s°F, sudden cool fronts are not uncommon, especially with the coastal breeze. Precipitation is a distinct possibility, with scattered showers or light rain occurring on several days throughout the month. The key to dressing for Boston in May is strategic layering. Think versatile pieces: short and long-sleeved tops, a light sweater or cardigan, and a medium-weight jacket. Comfortable, closed-toe walking shoes are essential for exploring the city's historic streets, and a compact umbrella or water-resistant shell will prove invaluable for unexpected drizzles.
