This unusual weather highlights the growing concerns of climate change and its impact on local heat patterns.

San Antonio Faces Unseasonably Early Heat Wave with Record Temperatures Expected This Week

San Antonio is bracing for an unprecedented heat wave, with temperatures projected to exceed 100 degrees starting May 13. This extreme weather event has raised alarms across south-central and southeastern parts of the United States, including Texas and Florida, where numerous areas are currently under extreme heat warnings.

The upcoming week’s weather is forecasted to reach triple-digit temperatures that are more akin to the sweltering days of August rather than the start of summer in May. On May 13, temperatures are expected to hit between 102 to 103 degrees, and the following day may even soar to 105 to 106 degrees, which could establish new record highs for the month.

Public Health Advisory and Cooling Centers

In response to the extreme heat, San Antonio has opened over 60 cooling centers across the city to provide residents relief from the oppressive temperatures. These facilities include city libraries, senior centers, and community centers, which are available to anyone seeking a refuge from the heat.

Health officials warn that prolonged exposure to high temperatures significantly raises the risks of heat-related illnesses such as heat exhaustion and heat stroke. It is essential for residents to recognize the signs of these conditions, with heat exhaustion manifesting as heavy sweating, weakness, nausea, dizziness, and headaches. Heat stroke, which can be life-threatening, requires immediate medical attention.

To safeguard against the heat, residents are advised to avoid strenuous outdoor activities during the hottest parts of the day and to take frequent breaks in shaded or air-conditioned spaces. It is recommended that individuals wear lightweight clothing, stay hydrated by consuming ample water, and utilize sunscreen to protect their skin from the harsh sun.

Record-Breaking Expectations

Historically, San Antonio has recorded temperatures hitting 100 degrees in May only 27 times over the past 140 years. The existing record high for May 13 is 98 degrees, set back in 1967, indicating that the forecasted highs have the potential to break this longstanding record. Over the last two decades, the city has averaged about 26 triple-digit days each year, illustrating a concerning trend in rising temperatures.

This year marks San Antonio’s first recorded 100-degree day in 2025, arriving significantly earlier than the average date of June 26. The Climate Prediction Center also foresees above-average temperatures continuing throughout the summer, predicting a strong likelihood of experiencing multiple days of intense heat this year.

Community Precautions

The unusual heat wave highlights the broader trends of climate change affecting weather patterns in San Antonio, where the prevalence of 100-degree days has risen sharply in recent years. Residents are encouraged to prepare adequately for the expected heat and prioritize their health and safety during this unseasonably hot period.
