Yuma is known as one of the sunniest locations in the United States. Our average annual rainfall is about 3 inches a year, making rain very unlikely to fall on any given day.
November through March are the most popular months to visit the park, with temperatures ranging from the 60s through the 80s. Springtime often brings windy conditions, although wind and sand storms can occur throughout the year. If the Yuma area receives substantial winter and/or spring rains, there is a good chance to see some Arizona wildflowers at the park. Common wildflowers include Spanish needles, brown-eyed primrose, and the desert marigold.
From April through October, Yuma temperatures climb into the 90s and 100s. April and May are the best months to view our prickly pear and saguaro cacti in bloom. June, July, and August tend to be the hottest months, with temperatures often reaching above 110. In July and August, Yuma enters into our monsoon season, which brings higher humidity—though little to no rain. After temperatures peak in July and August, they begin to drop back into the 90s and 80s during September and October.
