Welcome to the Georgia Weather Policy Guide, a handy resource for understanding the Georgia High School Association’s (GHSA) weather policies for athletics. We’ve made it simple: here’s the key information you need.
Source: GHSA By-Law 2.67 – Practice Policy for Heat and Humidity (2025–2026).
By-Law 2.67 sets specific on-site requirements for heat safety at every outdoor practice. These aren’t recommendations — they’re part of the statewide policy every head coach signs at the start of each season.
To keep students, youth and athletes safe, the following are required:
Football is the only GHSA sport with a formal acclimatization schedule. The five-day window begins five consecutive weekdays before the official start of the football season. Any athlete who misses five or more consecutive days of practice or games — for any reason — must complete a re-acclimatization ramp before returning to full activity.
First 5 Days of Practice
Re-Acclimatization · After 5+ Consecutive Days Missed
Meeting AAA heat stress requirements starts with accurate data. Perry Weather’s on-site WBGT and Heat Index monitoring tracks conditions continuously, so your staff always has the information they need to make the right call.
Your heat stress policy is only as good as your ability to communicate it in the moment. Perry Weather gives your staff the AAA policy framework, real-time alerts, and forecasting they need to make confident decisions all season long.
Perry Weather automatically logs every WBGT reading so you always have a complete picture of heat conditions across every practice, every session, all year long.
The WBGT is a comprehensive measure that combines air temperature, relative humidity, radiant heat, and air movement to assess heat stress conditions. Read more about WBGT here.
Wet bulb globe temperature in a nutshell is a more in-depth heat stress measurement taking into account more of the environment (Direct sunlight, water vapor capacity, cloud coverage, etc.). Read more about the differences between WBGT and the heat index here.
Monitoring WBGT is essential for protecting athletes’ health and safety during outdoor practices, games, and events.
A higher WBGT reading leads to a greater risk of heat-related illnesses like heat stroke, heat exhaustion, and muscle cramps.
Heat acclimatization is your body’s way of adapting to hot environments.
By gradually increasing your workload or exposure time in hot conditions over 1-2 weeks, you can significantly improve your heat tolerance.
This reduces the risk of heat stress and allows you to perform better in hot weather.
There are two main ways heat illness can strike:
1. Classic Heat Illness: This is caused by your environment’s impact on your body’s ability to cool down. Think high temperatures, humidity, direct sun, and no breeze.
2. Exertional Heat Illness (EHI): This one focuses on your own internal heat production. It can happen even in mild weather if you push yourself too hard.
Exertional heat stroke is the most severe form of heat illness and is a medical emergency. It occurs when your body overheats (usually above 104°F or 40°C) and can no longer cool itself down. This is often caused by strenuous physical activity in hot and humid conditions.
Wet bulb globe temperature involves measuring three temperatures: dry bulb, wet bulb, and globe. Read more here.
Imagine heat stress as a warning light on your body’s dashboard. If heat stress isn’t addressed, it can progress to heat illness. This is a medical emergency where the body can no longer cool itself down effectively. It can be life-threatening if not treated promptly. Read more here.
To measure WBGT, use a scientifically approved WBGT meter. The best way to measure it is by using Perry Weather’s advanced weather monitoring platform.
The following guidelines are based on recommendations by the Georgia High School Association:
At every outdoor GHSA athletic event, there must be a fully-functioning lightning detector that will be monitored by the Game Manager at a game, and a designated school person at a practice.
When a practice or game has been halted because of the detection of dangerous lightning, all participants should immediately go to a safe place.
The activity may not be resumed until thirty minutes after the last detected lightning strike in the danger zone.
Once play has been suspended, wait at least 30 minutes after the last thunder is heard or lightning is witnessed* prior to resuming play.
Any subsequent thunder or lightning* after the beginning of the 30-minute count will reset the clock and another 30-minute count should begin.
Perry Weather’s lightning detection and alerts system gives you clear, actionable instructions aligned with your lightning safety policies.
We’ll notify you as soon as lightning is detected with automated alerts. We guide you through immediate actions, keeping your athletes safe and practices on track.
Automatic alerts and real-time data for informed decision-making during critical weather events.
Know exactly when it’s safe to step out after a lightning strike with Perry Weather’s lightning countdown timers.
When a lightning strike is detected nearby, Perry Weather initiates a countdown until given the all-clear and resuming outdoor activities.
The timer resets with each subsequent strike, ensuring adherence to lightning safety protocols before resuming activities
Stay a step ahead with advanced radar and predictive lightning risk management for confident event planning and adaptive scheduling.
Get custom PA alerts and audible alarms with our lightning warning system.
Instantly broadcast alerts and safety messages automatically across your campus – no matter the weather conditions.
Strobe lights, loud alarms, and text-to-speech make sure you won’t miss lightning alerts.
It works even during power outages, ensuring continuous safety without needing a direct power source.
A safe shelter is any frequently inhabited building with four solid walls (not a dugout), electrical and telephone wiring, and plumbing, which aid in grounding the structure.
Yes. Lightning victims do not carry a residual electrical charge. However, prioritize checking for injuries and call emergency services immediately.
Responsibilities may vary, but typically coaches, athletic trainers, and officials share the responsibility for monitoring weather conditions and enforcing safety procedures.
Some policies allow for designated “safe havens” under sturdy structures like bleachers (away from metal supports) or inside enclosed vehicles with the windows rolled up. However, this is a last resort.
Watch how schools across Georgia are using Perry Weather to comply with state weather policies and keep their campuses safe.
