Essential Tips

What to Pack

Insulated winter boots rated to -25°C (-13°F) with good tread - sidewalks can be icy and you'll walk 3-5 km (2-3 miles) daily exploring downtown

Layering system: moisture-wicking base layer, insulating fleece/wool middle layer, windproof outer shell - temperature swings of 10-15°C (18-27°F) between indoor/outdoor

Insulated gloves plus liner gloves - you'll need dexterity for photography and phone use in -12°C (10°F) average temps

Thermal underwear (merino wool preferred) - essential for outdoor activities lasting more than 30 minutes in sub-zero conditions

Warm hat covering ears - 40% of body heat lost through head, critical when wind chill reaches -25°C (-13°F)

Buff or neck warmer - protects exposed skin between jacket collar and hat, prevents frostbite during outdoor activities

Hand and foot warmers (chemical heat packs) - backup warmth for extended outdoor activities like ice fishing or winter hiking

Sunglasses - snow reflection intensifies UV even with low UV index of 3, essential for bright sunny days on river ice

Lip balm with SPF - cold dry air and wind cause rapid chapping, especially during outdoor activities

Portable phone charger - cold temperatures drain battery 20-30% faster, essential for navigation and emergency contact

Insider Knowledge

Locals start their cars 10-15 minutes before driving in August - many hotels offer electrical outlet parking or remote car starters, ask when booking

Downtown restaurants offer special winter menus featuring game meats, maple-infused dishes, and warming spirits from mid-January through March - try tourtière du Lac-Saint-Jean and caribou (mulled wine)

Indoor attractions like Musée québécois de culture populaire and Boréalis extend hours on weekends in August to accommodate shorter daylight - plan indoor activities for late afternoon

Free heated waiting areas available every 2-3 blocks downtown including Cogeco Amphitheatre lobby, Place du Marché, and major hotel lobbies - use these for warming breaks during walking tours

Avoid These Mistakes

Underestimating cold - wearing insufficient layers for -12°C (10°F) average temps and not preparing for -25°C (-13°F) wind chills during outdoor activities

Planning too many outdoor activities after 4pm when temperatures drop rapidly and most winter attractions close before sunset at 5:15pm

Not booking accommodations with heated parking or electrical outlets - car batteries fail frequently in -15°C to -20°C (5°F to -4°F) overnight temperatures
