Annual Weather

Homolovi State Park is located in a basin surrounded by the Mogollon Rim to the south, the Hopi Mesas to the north, and the San Francisco Peaks to the west. To the east there is a gradual rise toward Gallup. As a result, Homolovi resides in a rain shadow. Although brief thunderstorms can move through the park, most rain bypasses the park and is seen only in the form of runoff. During the winter, there are often several overcast days in a row, but any snow normally melts off by about 10 am.

Winslow weather is known for high winds in the spring and fall, although wind can strike at any time of the year. Mornings are usually calm, with the breeze picking up at about 11 am, then calming down again at sunset. However, there are exceptions.

Most rain occurs during January and February, then again in July and August. Heavy flows of the Little Colorado River can take out the park water line, in which case the campground will be restricted to “dry camping” only, although restroom facilities will still be available (but with no showers).
