Calgary Weather Packing Guide — July

Calgary weather in July is generally warm and pleasant, but it can still throw a few surprises your way. Afternoon thunderstorms are common, and evenings cool off quickly, so it's wise to be prepared for changing conditions. Keep an eye on the local weather forecast as your visit approaches to make any last-minute adjustments to your packing. Here's a guide to help you pack and dress appropriately:

Temperature

Daytime highs typically range from 22°C to 26°C (72°F to 79°F), with occasional hot spells pushing into the low 30s°C (mid-80s°F). Nighttime lows are comfortable, usually dropping to around 9°C to 13°C (48°F to 55°F), so evenings can feel crisp.

Conditions

You can expect plenty of sunshine, but be ready for sudden afternoon thundershowers, gusty winds, and hailstorms — Calgary is known for its summer hailstorms. Most days are sunny and dry, with low humidity making the heat feel more comfortable.

What to Wear

The key to staying comfortable in Calgary's variable summer weather is layering and having rain protection on hand. We recommend:

• Lightweight tops and t-shirts for daytime, a light sweater or fleece for cooler evenings, and a waterproof or water-resistant jacket for unexpected downpours. Shorts are great for daytime, but jeans or pants work better for evenings.
• Comfortable walking shoes or sneakers are perfect for exploring. If you plan to hike or do outdoor activities, sturdy footwear with good grip is recommended — trails can get muddy after rain.
• A wide-brimmed hat or cap and sunscreen are essential for sun protection. Sunglasses are a must — Calgary is one of Canada's sunniest cities, with long daylight hours in July. A lightweight scarf or bandana can also be handy for wind or dust.

Don't Forget

• Sunglasses and high-SPF sunscreen
• Reusable water bottle (stay hydrated in the dry summer heat)
• Camera or smartphone for those stunning Rocky Mountain views
• Health essentials like hand sanitizer and insect repellent (mosquitoes can be active near water)
• Portable umbrella or compact rain poncho for sudden showers
