Catalina State Park is open all year, but is best enjoyed from October through May. The summer months of June through September are generally quite warm. During the fall, winter and spring months, daytime temperatures are mild with highs between 50 and 70 degrees. Overnight lows in January and February are below freezing, and occasionally drop into the teens. As is typical in the desert, a 40-degree swing between the daily low and high is not uncommon in winter. Daily high-low temperature swings during the summer months are not as extreme, with lows near 80 degrees and highs around 100 degrees. Rainfall is generally sporadic most of the year, but there is a rainy period July through September during which there are thunderstorms at least several times each week. Winter snowfall is very rare.
October through May is excellent weather for all types of outdoor activity because of the mild temperatures. Wildlife viewing is also best during the cooler months, as desert creatures are less active in the daytime heat of summer. Physical activities like hiking and bicycling should be confined to the very early morning during summer to avoid possible overheating and dehydration. Plan your wildflower viewing during March and April, but keep in mind that bloom quality can vary a great deal from year to year based upon winter rainfall.
