It’s easy to forget about types of weather that occur outside of our own backyards, especially during the summer months of sunshine. The wonders of our planet and its most essential resource never seize to amaze us, though, and that’s why we’re so fascinated by a summer weather phenomenon called monsoons.
A monsoon, according to National Geographic, is a seasonal change in the winds of the area that alter the climate of the region. This phenomenon is common in areas close to the Indian Ocean, like India, Sri Lanka, Bangladeshand Myanmar, but it also occurs in the southwestern United States. Clearly, our eight Aqua states don’t typically see this type of weather, so we’re extra curious about it!

There are two kinds of monsoons: dry and wet. A wet monsoon causes heavy rain in a region, while a dry monsoon does the opposite. This video from NASA does a great job of explaining how and why monsoons form.
Monsoons mostly affect North America in the middle of summer, from July to September. In fact, states like New Mexico and Arizona get half of their annual rainfall during monsoon season. Fun fact: The wettest monsoon recorded in U.S. history was in 1984, with 9.56 inches of fallen rain. These records include numbers traced back to 1896.
Usually, monsoons are beneficial to the areas they affect. Because these storms often occur after long periods of drought, the moisture they bring is replenishing and fruitful to the plants in the ecosystem. The high levels of rain can also aid firefighters battling wildfires in extremely dry areas.
Not all effects of monsoons are simple and benign, though. Since the affected land has often been bone-dry for so long, it can only soak up so much water at once. The rest of the water sits on top of the parched land, causing flash floods even from small amounts of rain. On top of flooding, monsoons can also bring lightning storms and massive dust storms called haboobs that can pose additional safety concerns for the affected communities, especially for people caught off guard while driving.
People who live in parts of the U.S. where monsoons occur are usually aware of necessary precautions. But for tourists, business travelers, or even new neighbors in the southwest, it’s important to know how to prep for monsoon season. In fact, paying attention to weather forecasts and having an emergency supply kit on hand are good summer weather tips for people living in any part of the country, especially during Hurricane Season.
