Perry Weather vs. Portable WBGT Meters

Your routine before and after Perry Weather

Perry Weather’s station monitors the weather for you — readings logged automatically, with zero labor.

Before Perry Weather

Disconnected and inconsistent

Every campus handles heat safety differently, with no district-wide standard
Coaches, band directors, and staff rely on word of mouth to know when to move indoors
Spotty, handwritten logs that can’t prove compliance if a parent or the UIL asks
No visibility into whether practices actually followed policy
Decisions made on guesswork, leaving the district exposed when something goes wrong

After Perry Weather

Perry Weather
One WBGT standard across every campus and every program
Automatic alerts reach every coach, director, and staff member at once — mobile and PA
Every reading logged automatically, with exportable records that stand up to scrutiny
District-wide visibility into conditions and compliance in real time
A defensible, documented heat safety program — always on, no one to chase down

Wet Bulb Globe Temperature Monitoring and Alerts

Alert your team and record everything with one system

Perry Weather is a two-part system, both Weather Station & Software Platform working together to accurately monitor, record and alert your team of heat risks.

Accurate On-Site Heat Sensors

A fixed weather station that measures true WBGT and heat index right where your people are without the need for manual monitoring.

Heat Monitoring Software

A web and mobile dashboard with live and forecasted conditions, auto-logging WBGT every 15 minutes for a defensible, paper-free compliance record.

Automated Heat-Stress Alerts

Knows your heat stress policies and work/rest ratios, then sends alerts with clear instructions, so your team knows exactly what to do the moment heat climbs.

Platform Features

Heat safety and policy compliance made effortless

Zero setup required, the weather station is always on

Never worry about having to set up tripods or do readings every 15 minutes during outdoor activities again. Perry Weather watches the heat for you and alerts coaches and band directors the moment they need to know.

Keeps your whole team up-to-date when the heat changes

Perry Weather sends alerts to everyone the moment your WBGT policy thresholds are crossed

Takes accurate readings that keep your team safe

Perry Weather stations include a precise WBGT monitor with a large 3.5″ black bulb sensor, offering more reliable readings than smaller handheld devices.

Records WBGT 24/7 for record-keeping & compliance

Perry Weather automatically monitors WBGT and records readings every 15 minutes, so you can ensure you’re in compliance without the hassle.

Monitor WBGT from anywhere — desktop or the mobile app

You don’t have to be out on the field to get a reading. Access live readings from the web dashboard or mobile app.

Frequently asked questions

Have questions about how Perry Weather monitors WBGT and heat stress? Check out some of our frequently asked questions.

A handheld depends on someone remembering to walk out, take a reading every 30 minutes, write it down, and file it — at every practice, at every site, all season. For programs required to monitor WBGT at every practice, an automatic on-site sensor eliminates the compliance risk that comes with manual methods. Perry Weather logs and timestamps every reading for you, so documentation is built in rather than dependent on a clipboard.

Yes. Instead of waiting on a manual reading, Perry Weather pushes a real-time alert the moment your site crosses into the next WBGT zone, so coaches and trainers can modify activity, start work-to-rest breaks, or move to the cooling zone right away. That removes the lag between “conditions changed” and “we found out.”

Wet bulb globe temperature measures heat stress in direct sunlight, giving a better idea of how the human body will react in hot and humid weather.
WBGT readings, unlike regular temperature readings, combine the effects of:
– Ambient Temperature
– Wind Speed
– Relative Humidity
– Solar Radiation

WBGT is a more practical, accurate, and useful measurement of heat as it relates to the body, especially when dealing with outdoor activities and sports programs.

Said plainly, WBGT is the best measurement to prevent exertional heat stroke and the effects of extreme heat.

There are two complex formulas involved in calculating Wet Bulb Globe Temperature. To truly get WBGT measurement right, having an on-site WBGT sensor like the one offered with Perry Weather’s weather station is one of the most practical ways to monitor & record WBGT while keeping students safe.

Perry Weather’s outdoor weather station is equipped with a more capable 3.5” diameter black bulb, providing precise and timely WBGT readings.

Unlike WBGT, heat index is a measurement that only takes into account air temperature and humidity. Think of it as the “feels-like” temperature in a shaded area. Heat Index is measured in the shade rather than the sun, and doesn’t factor in cloud cover (solar radiation), wind, or sun angle.

For situations where precision and heat safety are required, like in outdoor sports practice or outdoor events, WBGT is preferred. Learn more about heat index vs WBGT
