Insider timing tips
- •September and October offer the best combination of pleasant weather and stunning fall foliage, but come with peak season crowds and prices.
- •While summer (July-August) is warm, the high humidity and potential for heat waves can make extensive outdoor exploration uncomfortable.
- •The shoulder months of April and May offer a good balance before the summer rush, though May is significantly more pleasant weather-wise.
- •Boston's winter (December-March) is harsh and often snowy, leading to low crowds and prices, but also potential travel disruptions and limited outdoor activities.
- •Major events like the Boston Marathon and university graduation weeks (late May/early June) can cause significant local congestion and drive up accommodation costs.
