Lightning warning systems for courses and venues: sirens, alerts and sensors compared

Two jobs, not one

A lightning system has to do two separate things: see the storm coming, and tell everyone outdoors. Many buying mistakes come from solving only one. An alerting app is good at the first and weak at the second, because a guest on the 14th fairway doesn’t have your staff’s app.

The National Weather Service says every plan needs a designated monitor either way. These systems support that person. They don’t replace a written plan.

The options side by side

Option	Who it warns	Where it works well	What to check
Subscription alerts (text or app)	Staff and subscribers	Several sites, low setup	Guests and players without the app aren’t warned
On-site sensor with sirens and strobes	Everyone within hearing and sight	Signalling “clear the area” and “all clear” on site	Whether sirens cover every hole, range and parking area; who maintains them
Combined weather and lightning platform	Staff, plus on-site signals	One dashboard, logs, extra weather data	More to configure; ongoing subscription
Manual (designated monitor with radar and a phone)	Whoever the monitor reaches	No equipment cost	Depends entirely on one person being present and alert

Matching the option to the property

• A spread-out course or park: plan for on-site signals as well as staff alerts. One method rarely reaches every area.
• Several sites under one operator: a central alerting service and dashboard saves coordination.
• A venue with spectators: pair detection with a spectator-facing announcement plan, because most of the people at risk aren’t staff.

Questions to ask a provider

• What detects the lightning, and how is the alert distance set?
• Where would sirens and strobes go to cover every hole, the range and the parking areas?
• Who maintains the equipment, and what happens if a unit fails?
• Are warnings and all-clears logged?
• What is the contract term, and what happens if we cancel?
