Weather by month
Bar Harbor
Maine
A granite island town with a short, glorious season and a long quiet winter that most of the town simply sits out.
The best time to come
July through September is the whole show: August has the fewest damp days and the warmest sea, September the quietest trails and the best light. Early October brings the color, if you accept a lot of rain and a town already packing up.
