Spring weather is very
unpredictable. Stormy, wet days are common, but warm, sunny weather may
occur too. Precipitation peaks in March. Spring wildflowers bloom from
April through June, peaking in May.
Summer days are hot (95-110°F),
but overnight lows are usually comfortable (65-70°F). Afternoon
thunderstorms are common from mid-July through mid-September. Storms may
produce waterfalls as well as flash floods.
Fall days are usually clear and
mild; nights are often cool. Autumn color displays begin in September in
the high country. Colors in Zion Canyon usually peak in late October.
Winter in Zion Canyon is
fairly mild. Winter storms bring rain or light snow to Zion Canyon, but
heavier snow to the higher elevations. Clear days may become quite warm,
reaching 60°F; nights are often in the 20s and 30s. Winter storms can last
several days and cause roads to be icy. Zion roads are plowed, except the
Kolob Terrace road, which is closed in winter. Be prepared for winter
driving conditions from November through March.
