What to Pack for Salt Lake City: Essential Seasonal List

Quick answer

Pack moisture-wicking layers for summer (June-August, 27°C-35°C) and heavy insulated outerwear for winter (December-February, -5°C-4°C). Visitors to Temple Square or the Assembly Hall should bring modest attire covering shoulders and knees. Carry high-SPF sunblock for the 1,300m altitude and sturdy boots if hiking the Living Room Trail or Brighton Lakes.

Seasonal clothing and temperatures

Salt Lake City experiences four distinct seasons with significant temperature swings due to the high-altitude desert climate. Humidity remains low, which makes summer heat feel dry but winter cold feel piercing.

Summer (June to August)

Expect highs between 27°C and 35°C (80°F-95°F). Evenings in neighbourhoods like Sugar House or 9th and 9th often drop to 15°C. Pack lightweight linens, breathable cottons, and a wide-brimmed hat. A light jacket is necessary for sunset concerts at Red Butte Garden or outdoor dining at The Gateway.

Autumn (September to November)

Temperatures fluctuate between 5°C and 22°C (40°F-72°F). September is mild, while November often sees the first snowfall. Layering is essential. Pack a mid-weight fleece, a waterproof shell, and jeans. Sturdy shoes are required for leaf-peeping in Big Cottonwood Canyon.

Winter (December to February)

Daytime highs average 0°C to 4°C (32°F-40°F), with nights dropping well below freezing. If taking the 994 bus to Snowbird or Alta, pack thermal base layers, waterproof ski trousers, a heavy down parka, and wool socks. Salt and slush are common on downtown pavements; bring waterproof boots with traction.

Spring (March to May)

Temperatures range from 2°C to 18°C (35°F-65°F). This is the wettest season. Bring a high-quality raincoat and an umbrella for walking between the Salt Palace Convention Center and City Creek Center. Mornings are often frosty, requiring gloves and a beanie.

Cultural dress rules and modesty

Salt Lake City is the global headquarters of The Church of Jesus Christ of Latter-day Saints. While the city is secular and casual, specific sites require respectful dress. When visiting Temple Square, the Family Search Center, or the Tabernacle, follow these guidelines:

• Coverage: Shoulders, chest, and knees should be covered. Avoid sleeveless tops, tank tops, or short skirts.
• Style: Smart-casual is appropriate. Many locals wear 'Sunday best' (suits or dresses) for services, but clean trousers and a collared shirt or a modest blouse are sufficient for tourists.
• Footwear: Comfortable walking shoes are acceptable, but avoid flip-flops if entering formal buildings.

Electronics and plug types

Utah uses the standard North American Type A and Type B plugs. The voltage is 120V with a frequency of 60Hz. Visitors from the UK, Europe, or Australia will require a power adapter.

• Power Bank: Cold temperatures in the surrounding mountains drain phone batteries quickly; carry a portable charger if heading to the Great Salt Lake or Antelope Island.
• Camera Gear: A CPL (Circular Polarizer) filter is useful for managing the intense glare from the Salt Flats or snow-covered peaks.
• GPS: Download offline maps for the Uinta-Wasatch-Cache National Forest, as mobile signal is unreliable in the canyons.

Documents and visa notes

International travellers must adhere to US federal entry requirements. Most visitors from the UK, EU, and Commonwealth nations require an ESTA (Electronic System for Travel Authorization) under the Visa Waiver Program. This costs approximately $21 USD and must be applied for at least 72 hours before departure. Check the official US Customs and Border Protection site for current fees.

• Identification: A passport is required for all international arrivals at Salt Lake City International Airport (SLC). Carry a physical ID for age verification at bars and breweries, as digital copies are rarely accepted.
• Insurance: Medical costs in Utah are high. Ensure your policy covers 'high-altitude activities' if you plan to ski or mountain bike.
• Transport: A physical or digital copy of your car rental agreement is needed for the kiosks at the airport terminal. If using the UTA TRAX light rail, the 'Transit' app allows for mobile ticketing (approx. $2.50 USD for a one-way fare).

Health items

• Hydration: The air is exceptionally dry. Carry a reusable water bottle and drink more than usual to prevent altitude sickness.
• Sun Protection: The UV index is high year-round due to the elevation. Pack lip balm with SPF, sunglasses, and broad-spectrum sunscreen.
• Skin Care: Heavy moisturiser and saline nasal spray help combat the dry desert air, which can cause cracked skin or nosebleeds in newcomers.
• Altitude Medication: If you are prone to altitude sickness, consult a doctor about acetazolamide before ascending to the ski resorts (which sit above 2,400m).

Common mistakes

• Underestimating the sun: The mountain air feels cool, but the UV rays at 1,300m+ cause rapid sunburn even in winter.
• Ignoring the dry air: Failing to use moisturiser and drink extra water often leads to headaches and fatigue within 24 hours of arrival.
• Inadequate footwear: Bringing only fashion shoes or sandals. The terrain in nearby parks like Liberty Park or City Creek Canyon requires support.
• Dressing too light for evenings: Desert temperatures drop quickly once the sun sets behind the Oquirrh Mountains.
• Forgetting ID: Utah has strict liquor laws; even those clearly over 21 will be asked for a physical ID at venues like Fisher Brewing Company or The Bayou.
