Phoenix Braces for Record-Breaking March Heatwave – and St. Patrick’s Day Celebrations
Phoenix residents are facing an unusual combination this week: soaring temperatures, and St. Patrick’s Day festivities. A prolonged heatwave, with temperatures 20-30 degrees above average, is expected to grip the Valley from Tuesday through Sunday, prompting an Extreme Heat Warning from the National Weather Service.
Triple-Digit Temperatures Arrive Early
Tuesday, coinciding with St. Patrick’s Day, will see highs in the upper 90s. However, the real heat arrives Wednesday, with a projected high of 102 degrees – potentially marking Phoenix’s earliest triple-digit day on record. The current record for the earliest 100-degree day is March 26, 1988. Temperatures are forecast to remain between 102-106 degrees through the weekend.
Hiking Trail Closures and Safety Concerns
The extreme heat is already impacting outdoor activities. Popular hiking trails, including Piestewa, Camelback, and parts of South Mountain, will be closed from 8 a.m. To 5 p.m. Daily. Authorities urge residents to stay hydrated and take breaks from the sun if outdoor plans are unavoidable. This heat warning is the earliest on record, surpassing the previous instance between April 26 and April 30 of 2020.
Record-Breaking Streak
Phoenix is poised to break high-temperature records for six consecutive days:
- Wednesday: High of 102, record is 95 degrees (2017)
- Thursday: High of 104, record is 96 degrees (2017)
- Friday: High of 105, record is 96 degrees (2017)
- Saturday: High of 106, record is 97 degrees (2004)
- Sunday: High of 103, record is 94 degrees (1990)
- Monday: High of 98, record is 93 degrees (1990)
Beyond Phoenix: Regional Impact
The heat isn’t limited to Phoenix. Even Flagstaff will experience temperatures nearly 30 degrees above average, with highs reaching the 80s, significantly warmer than the typical 50s for this time of year. The heatwave is attributed to a ridge of high-pressure settling over the region.
St. Patrick’s Day Festivities Continue Despite Heat
Despite the extreme temperatures, St. Patrick’s Day celebrations are still planned. The annual St. Patrick’s Day Parade and Faire took place on March 14th, featuring Irish music, dancing, and community events at Margaret T. Hance Park. Irish pubs across the Valley, like Séamus McCaffrey’s and Tim Finnegan’s, are expected to be busy on March 17th.
