Climate

Where summer spends the winter...  warm days (60s F) and chilly nights (40s F) are common during late fall to early spring.  When there are consistent winter rains the spring wildflowers will be spectacular. Early summer days are hot and dry with temperatures in the 100s and humidity below 10%.  Late summer monsoons bring fantastic lighting and furious thunderstorms.  Temperatures drop into 90s, however the humidity increases.  Most of our visitation happens between December and March.  If you visit during the summer you may want to plan on getting up early and taking an afternoon siesta in the shade.

A photo of a barrel cactus with flowers

Did You Know?
It's not easy, practical, or legal to get "water" from a barrel cactus within the Monument. Even if you tried to get past the spines, it would be like sucking on a bad-tasting dish sponge. The best thing to do is fill a canteen with good drinking water before leaving home.
