All Months
Summer festivals turn Montreal into one giant party. Jazz Fest, Just for Laughs, and Osheaga pack the calendar from June through August. But everyone knows this — hotels triple their rates. May and September offer perfect weather without the crowds. Fall colors peak in late September, especially on Mount Royal. October brings crisp mornings and cozy café afternoons. Winter is brutal but magical. Temperatures hit -20°C regularly, but the city doesn't hibernate. Underground passages keep you warm, outdoor rinks pop up everywhere, and Igloofest makes electronic music in sub-zero temps somehow work. Spring arrives late — don't trust April weather forecasts.
