Heat Waves Leads Some School to Close or Dismiss Classes early

In recent years, an unexpected phenomenon has been sweeping through schools across the United States. While snow days have long been the bane of teachers and the delight of students, it seems that heat days are now taking center stage. With rising temperatures, especially in the early and late summer months, schools without adequate air conditioning are grappling with how to protect students from the scorching heat. In this article, we’ll delve into the challenges posed by heat days and explore the implications for the education system.

The Heat Wave Phenomenon

As late-summer heat waves become more intense, temperatures in parts of the Northeast and Midwest are reaching record-breaking highs for early September. This surge in heat is no longer confined to the traditional summer months, putting pressure on schools as they struggle to adapt. Schools lacking reliable air conditioning are finding themselves in a tough spot, resulting in canceled classes, adjusted schedules, and the suspension of after-school activities to ensure the safety of students.

Preparing for Extreme Weather

The trend of heat days potentially becoming the new snow days is gaining momentum as global temperatures continue to rise. Experts warn that schools must prepare for extremes on both ends of the weather spectrum. Kevin Lanza, an assistant professor at UTHealth Houston School of Public Health, predicts an increase in days with extreme heat that will overlap with the typical school year. This shift necessitates proactive measures to safeguard students and their education.

The Impact on Learning

Heat isn’t just a health risk; it also has a profound impact on learning. A 2018 study from the Harvard Kennedy School revealed that in schools without air conditioning, students’ academic performance declined by 1% for every 1-degree Fahrenheit increase in temperature. This underscores the urgency for schools to address the challenges posed by extreme heat.

The Call for Climate Change Preparedness

Laura Schifter, a senior fellow at the Aspen Institute, emphasizes that schools need to consider how climate change will impact them. Developing and implementing plans to respond effectively to these changes is crucial. Schools must adapt their infrastructure and policies to provide a safe and conducive learning environment, even in the face of rising temperatures.

A Parent’s Concern

Patricia Burton, a concerned parent from Baltimore, highlights the struggles students face when schools lack proper cooling systems. Her 9-year-old son, Delano, attends a school without adequate air conditioning, putting his health at risk, especially considering his asthma. Patricia’s concerns echo those of many parents who worry about their children’s well-being in sweltering classrooms.

The Unprecedented Heat

Baltimore, for instance, is experiencing historically high temperatures, with forecasts predicting a staggering 101 degrees. Schools in the city, including Delano’s, are responding with early dismissals to protect students from the heat. These extreme temperatures have been a rare occurrence, making the need for effective cooling solutions more urgent.

Widespread Disruptions

The heatwave isn’t limited to Baltimore; it’s affecting schools across the Midwest as well. Cities like Milwaukee, Chicago, and Detroit are adjusting schedules or closing due to the punishing heat. In Philadelphia, where September temperatures have never exceeded 95 degrees Fahrenheit, dozens of schools are dismissing students early due to inadequate cooling.

The Road to Change

Recognizing the complex challenges of climate change and outdated school infrastructure, experts stress the importance of updating school buildings to withstand extreme heat. It’s not as simple as installing air conditioning units; the entire building must be adapted to modern climate conditions.

Innovative Solutions

Community advocates in some states are taking proactive steps to create healthier and safer environments for students and teachers. These efforts include transforming heat-absorbing asphalt into green spaces with ample shade and adopting heat pumps instead of traditional fossil fuel-powered air conditioners. Such initiatives aim to ensure that students can learn comfortably while reducing reliance on fossil fuels.


As the effects of climate change become increasingly evident, schools must adapt to protect students from extreme heat. Heat days could indeed become the new snow days, necessitating innovative solutions and infrastructure upgrades. Learning in a safe and comfortable environment is a fundamental right that must not be compromised.
