Description:
AQAPSR
The Arizona Department of Environmental Quality (ADEQ) has extended
an Ozone High Pollution Advisory for the Phoenix Metro Area through
Friday.
This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.
Ozone is an air contaminant which can cause breathing difficulties
for children, older adults, as well as persons with respiratory
problems. A decrease in physical activity is recommended.
You are urged to car pool, telecommute or use mass transit.
The use of gasoline-powered equipment should be reduced or done late
in the day.

stroke. Wear lightweight and loose-fitting clothing when possible and
drink plenty of water.

About Phoenix
Phoenix is a central metro planning page for city mountain preserves, paved paths, desert parks, outdoor events, patios, and short trail windows around the Valley of the Sun.
Make the Most of a Phoenix Day
Plan around heat first. In warm seasons, choose early starts, shaded or short routes, and backups close to town. During stormy monsoon periods, dust, lightning, and flooded washes can matter as much as temperature.
Weather Tips for Phoenix
- Extreme heat, strong sun, limited shade, urban heat, dust storms, lightning, flash flooding in washes, and poor air or smoke can all affect Phoenix outdoor plans.
- In warm seasons, start early, shorten exposed routes, and carry more water than a casual city forecast might suggest.
- For biking, watch heat, wind, trail exposure, and whether recent rain has left rock, clay, or desert paths slick.
- Smoke, dust, and fire restrictions can change plans during dry and windy stretches, especially away from town services.
Nearby Towns and Areas
This page is meant to cover a roughly 25-mile outdoor-planning area around Phoenix, including central Phoenix parks and preserves, South Mountain, Papago Park, canal paths, and close-in metro outdoor event areas. It can also be useful when planning outdoor time near:
- Phoenix Mountain Preserve
- South Mountain Park
- Papago Park
- Camelback Mountain area
- Encanto Park
- Arizona Canal paths
- Downtown Phoenix
- Tempe approaches
Plan Around the Conditions
Use the forecast to choose the best version of Phoenix rather than forcing one itinerary. Match heat, sun exposure, wind, storm timing, water conditions, trail surfaces, fire restrictions, elevation, and road conditions to the activity that gives your group the most comfortable day.
