What October feels like
Color peaks around mid-month and later than inland Maine, so a leaf trip can do the mountains first and the coast afterward. This is also the month that turns over the most rain here, and the wind that comes with a coastal storm strips the trees in an afternoon.
Expect about 7 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy. about 6 nights dip below freezing.
Can you swim?
The ocean runs about 57° — frigid — locals in wetsuits only.
