Grant County is a remarkably diverse landscape, ranging from open desert at 4000
feet in elevation in the south to mountains over 10,000 feet across the north of
the county. Temperatures are generally mild, giving us four gentle seasons to enjoy.
Fall usually starts around the end of September and a first
freeze in October is not out of the question. Fall colors can
be spectacular: Above 7000 feet the County has aspens and below
that level cottonwoods, providing a range of brilliant colors
framed against our deep blue skies. A Fall trip just to see
mountain colors is well worth considering!
Winter is typically cool and clear. We occasionally see snow
during the winter, although it is gone from the roads quite quickly.
Higher in the mountains and in parts of the County above 7,000 feet,
snow may persist for several days; at these times, planning ahead
for remote travel — and especially for off-road travel —
is advisable. On many winter days, the temperature can get to
shirt-sleeve weather when out hiking or working. Nighttime temperatures
in the 20s are common.
Spring is usually dry and may be windy. Wildflowers and other
desert plants can provide a fantastic springtime show, depending
upon winter moisture. Late Spring is often very dry, so there
are typically no bad-weather days. Nighttime temperature can
remain chilly into late May.
Summer starts in June with temperatures in the 80s and low 90s. June
and July are typically the warmest and driest months. Even then,
temperatures rarely get to 100. Beginning sometime in July,
the seasonal monsoon rains start, so afternoons can be cooler
and moister after a thunderstorm.
