Fall River is pretty lovely on these hot days. I think it is too cold to wet wade, even on a day in the mid-90’s. But dipping in that freezing cold water with shorts on under your waders and you wont last an hour in the water before coming out to warm up. 

How’s the fishing? Its ok to pretty good. I’d recommend going early in the morning or going the last couple of hours before dark to avoid the bigger crowds. If that isn’t in the cards, and hitting the river mid-day is, you will find good fishing then too. 

Euro Nymphing is best. PMD’s, Olive Caddis, BWO’s, Yellow Sally’s, Ant’s, Beetles, small Hopper’s and Rusty Spinners are going to be your various dry fly options from morning to dark.
