Grand Canyon National Park: Last Snowman of Winter?

Saturday, March 9th. Viewing a spectacular sunset as a Pacific storm breaks up. Could this be the last snowstorm of the season? With warming temperatures in the forecast all week, spring may be arriving at last. NPS Photo by Erin Whittaker.


By mid-April at Grand Canyon, winter weather usually begins to break, and although snow is not uncommon in May, warm spells become more frequent.


The winter cold gives way to a warming and pleasant spring period with average high temperatures gradually rising from the 50s and 60s (10-21°C) in April through the 70s to 80s (21-32°C) by June along the Rim, and from the 80s (27-32°C) in April to near 105 (41°C) by June along the river.


Low temperatures will typically fall below freezing on the Rim in April and May and warm into the 40s (4-9°C) by June, with low temperatures from the 50s (10-15°C) in April to the 70s (21-26°C) by June along the river.


Spring is typically breezy to windy with winds occasionally gusting over 40 mph (18 m/s) and dry with little precipitation occurring in May and early June. Due to the very dry airmass typical of the late spring months, late season frosts and freezes are still a possibility, with sub freezing temperatures being recorded as late as July at the North Rim. Snowfall has been reported as late as the middle of June.
