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.
