On Oct. 12, 2025, the remnants, also known as “runoff”, of Hurricane Priscilla hit Phoenix and the surrounding areas. The storm runoff led to a massive amount of rain that struck the Phoenix metro area. According to 12News, this October is the 4th wettest October on record for Arizona. As of Oct. 13, Arizona faced just over three inches of rain. In comparison, the wettest October occurred in 2018, when Phoenix received 5.35 inches of rain.  

One interesting detail about measuring rain is that one place can get more rainfall than another, which is why the city of Phoenix has decided to measure all of their rain at the Sky Harbor airport. Although this can be less representative of the rest of the valley, precipitation has been measured there since 1954. Using the strategy ensures a way to keep track of climate history, since it’s always measured in one spot. According to ABC15, some parts of Arizona got up to 4.61 inches of rain throughout the month. 

This amount of rainfall isn’t just blowing minds, it’s also breaking records. Before, the daily record for most rain in one day for Phoenix on Oct. 12 was 0.52 inches of rain set in 1957. The runoff from Hurricane Priscilla boosted this number to two inches, almost quadrupling the old record. 

As some might not know, it’s not only Arizona experiencing strange weather, it’s the whole world. This is a phenomenon known as “global weirding”, which could be tied to climate change. This is because climate change doesn’t only make areas generally warmer, but also causes extreme and fluctuating weather, such as abnormal rainfall and cold temperatures. However, proving this is difficult without extensive proof. To combat this, NASA has created climate models so they can personally see the change and inform the public. 

Earth is experiencing global weirding, and the people of the Phoenix metro area are experiencing this first hand. This is one of the first major signs of global weirding, and it’s not the last. As such, the people of Phoenix can be expecting more and more weird weather. 

As this weather continues to shock many, it breaks records, and rewrites how people think of weather in phoenix.
