Traveller notes on Montreux in May
Other months in Montreux
Montreux's forum calls June genuinely variable, sometimes warm enough to swim in Lake Geneva, other times cool enough to need a raincoat with a liner. Regulars' standard advice is to check the forecast the week before rather than assume, pack layers including a sweater or vest, and remember sun can still burn on a walk even when the air feels cool.
