PHOENIX – As monsoon season begins in the southwest, Arizona State Parks and Trails reminds the public to stay vigilant and prioritize safety while enjoying the outdoors. Monsoon season runs from June 15 through September 30, bringing increased potential for dust storms, dangerous lightning, flash flooding, and wildfires sparked by dry lightning or human activity.

While longtime residents may associate storms with July or August, monsoon season refers to a seasonal wind shift—from a dry westerly wind pattern to a moist southerly flow. This change sets the stage for extreme and often unpredictable weather events. According to the National Weather Service, above-normal rainfall is anticipated in many parts of Arizona this year, increasing the risk of flooding and related hazards.

Visitors to parks, trails, and waterways are urged to check weather forecasts before heading out, remain flexible with their plans, and seek shelter immediately when storms develop. Arizona’s high temperatures that usher in monsoon thunderstorms also pose serious risks. Low desert areas have already experienced heat-related rescues, and the entire state is expected to see above-average temperatures through September.

To stay safe, outdoor enthusiasts should remember to hydrate, avoid being outside in extreme temperatures, especially during the hottest part of the day from 10 a.m. to 5 p.m., wear sun protection, never leave pets or children inside a parked vehicle, check on neighbors, and be familiar with available heat resources, like statewide cooling centers.

Campers and hikers should take extra care when selecting locations to recreate. Avoid low-lying areas, washes, or flood-prone zones. Parks such as Catalina State Park, which sits near washes and fire-scarred terrain, are especially susceptible to flash flooding. Be proactive about checking the weather and making smart recreation decisions, like evacuating the area prior to conditions becoming dire. Fast-moving water is extremely dangerous—just six inches can knock an adult off their feet, and 18 inches can carry away most vehicles. Never attempt to cross a flooded trail or roadway.

As beautiful as Arizona's monsoon thunderstorms are, they are also powerful and unpredictable. Arizona State Parks and Trails encourages everyone to take personal responsibility for their safety by staying informed, preparing appropriately, and making smart decisions before and during their visit. With thoughtful planning, the beauty of Arizona’s parks and landscapes can be enjoyed safely all summer long.

Connecting people to the outdoors and history of Arizona to build a lifetime of memories.
