School Start Dates and Heat Concerns

Across the United States, more school districts are beginning the academic year in July or August. This change increases the chance that students will experience extremely hot weather. Recent data highlights the impact of these early start dates, particularly in regions with scorching summer temperatures.

In July 2026, Phoenix recorded a temperature of 117 degrees Fahrenheit, or 47 degrees Celsius. Despite the heat, children were seen walking to school, participating in outdoor recess, and gearing up for baseball practice. These activities expose them to significant heat-related risks.

“It’s crucial to consider how such extreme temperatures affect students’ health and learning,” said experts from The Conversation, a nonprofit news organization that provides insights from researchers and scientists.

Parents and educators in these areas are increasingly concerned about the safety and well-being of children during such hot weather. As schools open earlier in the summer, they must implement measures to protect students from the heat.
