SALT LAKE CITY, Utah – The Wasatch Mountains glow pale pink against a crisp Halloween dawn, with clear skies stretching across the valley and faint traces of fog drifting near the Great Salt Lake. The air feels calm and cool, a fitting start to what will be one of the region’s most comfortable late-October days in years.
The National Weather Service in Salt Lake City calls for sunny skies and highs near 61°F through the day — ideal for trick-or-treating or outdoor Halloween events. Winds stay light, and visibility across the I-80 corridor will remain excellent for evening travel. Costumes can stay light tonight, as temperatures hover in the mid-40s by late evening under mostly clear skies.
The mild weather continues through Saturday and Sunday, with highs climbing toward the upper 60s under steady sunshine. By late Sunday, weak clouds drift back into the region as early model guidance begins hinting at a midweek system.
Early next week, attention turns to a possible first November pattern change. While no snow is expected in the Salt Lake Valley yet, light rain could develop by Wednesday evening as Pacific moisture lifts into northern Utah. Temperatures remain seasonable through midweek, ranging from the upper 60s by day to the mid-40s at night.
For now, residents can expect a classic Utah Halloween — crisp mornings, golden afternoons, and calm evenings — before November brings the season’s next slow but steady turn toward winter.
