PHOENIX – It’s a hot week in the Valley of the Sun!
The high pressure disrupts the monsoon humidity and temperatures rise rapidly.
Warnings about excessive heat apply in the valley on Wednesday, Thursday and Friday. So we are in ABC15 Weather Action Mode as a reminder to take steps to stay safe in this dangerous heat.
Limit your time outdoors between 11 a.m. and 5 p.m., stay hydrated, and never leave children or pets in the car, no matter how quickly you need to run an errand.
Temperatures in the valley will reach record highs in the coming days and we will probably see a few more days of 43 degrees Celsius this year.
We’ve already had 55 days of 43 degrees or more this year, which matches the all-time record we set last year. We’ll break that record on Thursday and probably reach the 57th day on Friday.
And there’s no end in sight to this record streak of days with triple-digit temperatures. As of Wednesday, we’ve had 101 consecutive days with triple-digit temperatures. The previous record was 76 consecutive days with triple-digit temperatures, set in August 1993.
The meteorological summer ended on August 31st, and it was the hottest summer on record in Phoenix! The average temperature for June, July and August totaled 98.9 degrees, surpassing last summer’s record of 97.0 degrees.
Air quality is also a topic this week. Warnings of high ozone pollution apply to the valley today and tomorrow.
Ozone pollution can cause a variety of health effects. Children, older adults and people with asthma, COPD or bronchitis are most vulnerable, but even healthy adults exercising outdoors may experience symptoms such as chest pain, cough, throat irritation, congestion or shortness of breath.
Exposure to ozone can increase the number and severity of asthma attacks, cause or worsen bronchitis or other lung diseases, and reduce the body’s ability to fight infections.
You can help reduce ozone pollution by driving as little as possible, carpooling and using public transportation. Also, fill up your car after dark and avoid long lines at drive-thru stores to prevent worsening the pollution problem.
