What you need to know about the monsoon season
Updated
Lightning and Ocotillo meet as a late evening storm moves across Oro Valley towards the Tucson Mountains on July 8, 2018 north of Tucson, AZ.
Ron Medvescek / Arizona Daily Star1. When does it start?
Updated
Lightning touches down with a rain cell northwest of town on July 31, 2017, west of Tucson, Ariz.
Mike Christy / Arizona Daily StarSince 2008, the National Weather Service has decreed a monsoon season from June 15 to September 30. However, it still keeps track of the monsoon start by a measure it used from 1949 until 2008 — the first of three consecutive days with an average dew point of 54 or above.
Also known as chubasco, the summer rains bring much-needed moisture and cooler evenings. Not to mention lightning, heavy rain, high winds, flash flooding, hail and dangerous driving conditions.
2. Driving tips

Kelly Presnell / Arizona Daily StarIf you are caught in a severe storm and can’t drive safely, move completely off the road and stop with your lights off. Take your foot off the brake to make sure your brake lights aren't lit. This prevents other drivers from following your tail-lights, thinking you are still on the road. Never stop in the travel portion of the road.
Pro tip: Replace your windshield wipers before the monsoons start.
3. Be safe taking those awesome lightning photos
UpdatedOn average, 47 people die after being struck by lightning in the United States, according to the National Weather Service. Arizona made up for one of those deaths during 2016's monsoon season.
The incident occurred mid-July in Coconino County while the individual was hiking.
Monsoon lovers should take cover when watching storms from afar. Most lightning strikes occur more than three miles away from the center of the thunderstorm, and have even been spotted as far as 15 miles.
Some tips to stay safe during nature’s light show include: stay indoors when you hear thunder, avoid using plumbing and electrical equipment and keep your distance from windows.
You can also keep track of lightning strikes recorded in your area at lightningmaps.org

4. Say hello to your desert neighbors
Updated
Gila monster seen along a trail at Ventana Canyon.
Doug Kreutz / Arizona Daily StarExpect to see more Gila monsters, and other wildlife, come out to play on nights of high humidity.
According to the Arizona-Sonora Desert Museum, Gila monsters live in washes that extend down into the valley.
But don't freak out. They're just out enjoying the weather like everyone else.
5. Monsoon season scent
Updated
John Durfield, a retiree from Oregon, leans over to smell a creosote bush at Saguaro National Park.
A.E. Araiza / Arizona Daily Star 2010Have you ever wondered why it smells so good after a rainy day? The smell actually comes from the creosote bush, which has medicinal properties.
While you’re waiting for the rain to hit or can’t get enough of the smell, buy yourself some creosote-scented lotion or ointment.
6. End of Monsoon is the beginning of prickly pear season
Updated
Blooming prickly pear cacti add a splash of color near a crested saguaro in Sabino Canyon.
Doug Kreutz / Arizona Daily StarWith plentiful rain comes the beautiful green vibrance of the Sonoran Desert and the ruby red fruit of the prickly pear cactus.
This unique fruit, called a "tuna," grows from the pads of the cactus, creating an amazing edible crown that’s ready to harvest in September.
Tunas are used in a variety of foods and products, but some of our favorites include the prickly pear margarita at Reforma Cocina y Cantina, jellies and lip balm.
7. Monsoon Safety Awareness
UpdatedIt’s Monsoon Awareness Week! Follow along with us and the other southwest NWS offices this week to learn about Monsoon weather & how to stay safe from the hazards that it can bring. #azwx #Monsoon2018 #MonsoonAwarenessWeek pic.twitter.com/RwZOuJ3MlR

Just because Monsoon Safety Awareness Week is over, doesn't mean you shouldn't be careful during a storm.
8. You can follow the Tucson Monsoon on Twitter

Yep, this is a thing. And it’s awesome.
You can talk one-on-one with @ElTucsonMonsoon about everything from rain gauges to weather jokes. But mostly, it’s a lot of taunting hot Tucsonans.
