April 5th sits right in the heart of Holladay's wettest week of the year, so that 30% chance of rain is no coincidence. Historically, the date swings hard — from a balmy 84° back in 1959 to a brutal 16° low in 1955. Expect a mild spring day on average, but pack a layer just in case.
Holladay runs the full extremes of a high-desert valley climate, from a scorching 108° in July 1958 to a bone-chilling -15° in January 1963. The wildcard is fall: a single October day in 1984 dumped 25 inches of snow, and September 1982 unleashed 4.65 inches of rain in one go.
Summer is the main event here, with highs peaking around 92–93° in mid-July and staying in the 90s through August. Winters are cold but not brutal, with January highs averaging just 37°–39°. Spring — especially early April — is the wettest stretch of the year, while fall offers a sweet spot of warm days before the snow arrives fast.
