Salt Lake City eases into Sunday, May 31, 2026, under clear skies and a crisp start, with temperatures sitting in the mid 50s at local observation sites and a forecast high near 74°F this afternoon. Winds stay light, the valley looks mostly sunny, and it is just about perfect for outdoor plans or knocking out errands. The calm, however, will not last long, as a steady warmup settles in through the week.
Afternoon Sunshine, Mild Start
Temperatures climb through the morning into the low to mid 70s by late afternoon, helped along by north-northwest breezes generally under 10 mph. Humidity remains low, so the air feels dry instead of sticky or muggy. If you are heading out early, a light layer will still come in handy for those cooler morning hours.
Heat Builds This Week
Starting Monday, June 1, 2026, the warmup becomes more noticeable, with a high near 80°F and a slight chance for afternoon showers or isolated storms after 3 p.m. Temperatures then climb into the mid 80s by Tuesday and Wednesday and reach the upper 80s to low 90s by the weekend, with Saturday, June 6, currently trending as the hottest day. The National Weather Service Salt Lake City notes that the probability of a moderate HeatRisk rises through the week, which increases impacts for older adults, people with chronic illness, and anyone without reliable cooling.
Fire Weather And Dry Fuels
Hotter days are not the only concern. Dry air and poor overnight humidity recovery will elevate fire danger in parts of the state. Locally critical fire weather is possible across portions of southern and eastern Utah Monday afternoon and evening, June 1, and a broader window for critical conditions may arrive Thursday, June 4. By midweek, afternoon relative humidities could fall into the low teens in many valleys, making small sparks and careless activity more dangerous than usual.

Plan For The Week
To stay ahead of the heat, shift strenuous outdoor work and exercise to early morning or evening, keep water handy, and check in on neighbors who may be more vulnerable to rising temperatures. If you do not have air conditioning, look for community cooling spaces and confirm hours with local officials before you go.
