Salt Lake City starts Wednesday, July 1, under clear, dry skies, with valley temperatures sitting in the 60s and a fast warm-up on deck for the afternoon. Forecast highs are near 89°F, paired with light south-southeast breezes and low humidity that will leave the air feeling extra dry by later in the day. Overnight lows are expected to linger in the low 60s through the week, which means only modest cooldowns after sunset. With the pattern trending hotter into the holiday weekend, it is a good time to plan any midday outings around the rising heat.
Afternoon Heat Through The Weekend
Highs are expected to land around 88 to 89°F on Wednesday, then climb into the low 90s by Friday. By Sunday and early next week, readings are projected to reach the mid to upper 90s, with Saturday, July 4, targeting a high near 93°F. The National Weather Service notes only a slight chance of showers through the week, so most days should stay sunny. If you are planning barbecues, hikes, or yard work for the holiday, shifting the heaviest activity into the morning or evening will help you avoid the peak heat.
Fire Weather Concerns
That dry air, paired with gusty afternoons, is expected to push fire-weather risk higher across parts of central, eastern, and southern Utah later this week. The strongest and most widespread winds are possible on Friday. Overnight humidity recoveries are forecast to be poor to very poor from Friday into the weekend, which increases the odds that even a small spark could spread quickly. Anyone considering outdoor burning, fireworks, or campfires should review local rules and restrictions and use extra caution.
Cooling Options And Safety Tips
Salt Lake County keeps an updated list of public "Cool Zones" and cooling centers for residents who need a break from the heat. You can find locations and hours on the county’s Cool Zones page. Light, loose clothing, plenty of water, and limiting outdoor work during the midafternoon can go a long way, and it is worth checking in on vulnerable neighbors as temperatures climb. We first flagged this warming trend in our earlier warning on June 21, and the same pattern is now rolling right into the holiday week, as per Hoodline.
