Key Takeaway Does a Tracker Work During a Storm or Bad Weather?
• Yes. A GPS tracker keeps working in rain, wind, fog, snow and storms, because everyday weather has very little effect on GPS signals.
• Heavy downpours can slightly weaken the signal for a short time, but for vehicle tracking the difference is negligible.
• The bigger risks in bad weather are snow or ice covering a portable unit, mobile network outages, flat batteries in the cold, and water damage to poorly sealed devices.
• Severe solar storms (space weather) can reduce GPS accuracy, but these are rare in the UK and usually short-lived.
• A professionally fitted, hardwired tracker with a backup battery is the most reliable choice whatever the weather.
Yes, a tracker works during a storm or in bad weather. GPS satellites send signals that pass through cloud, rain and snow with only a tiny loss of strength, so your tracker can still find your vehicle’s position when the weather turns. Where problems do occur, they are usually caused by the tracker’s setup rather than the weather: a portable unit buried under snow, a battery drained by freezing temperatures, or a local mobile network outage that delays location updates. Whether you rely on hardwired car trackers or portable GPS trackers, here is what really affects performance when the weather is at its worst.
How a GPS Tracker Works
A vehicle tracker does two jobs:
- It works out where it is by receiving signals from GPS satellites orbiting the Earth.
- It reports that location to your app or a monitoring centre, usually over the mobile network.
Weather can affect each part differently, so it helps to look at them separately.
Does Rain, Cloud or Fog Affect GPS?
For everyday use, no. GPS signals are designed to travel through the atmosphere, including cloud, fog and rain. Very heavy rainfall and thunderstorms can lower the signal quality slightly, and scientists have measured this effect with sensitive equipment. For vehicle tracking, though, the change is far too small to stop a tracker from locating your car.
In other words, a typical British downpour is not going to make your car disappear from the map.
Snow and Ice
Snow and ice are a slightly different story. Water absorbs GPS signals, so a thick layer of snow or ice sitting directly over a tracker’s antenna can reduce accuracy.
This mainly affects portable or magnetic units fitted on the outside of a vehicle, trailer or caravan. Hardwired trackers hidden inside the vehicle are rarely affected, because they are not exposed to a build-up of snow.
Cold Weather and Battery Life
Low temperatures reduce battery performance. This matters in two ways:
• Battery-powered trackers may run down faster in winter, so they may need charging more often.
• Your car battery can struggle in freezing weather. A hardwired tracker with its own backup battery will keep reporting even if the main battery goes flat.
If you use a portable tracker through the winter, check its battery level more often and set up low-battery alerts in your app. Browse our car trackers for hardwired options with backup power, or compare the battery life of our portable GPS trackers to find one that suits your needs.
Mobile Network Outages During Storms
Your tracker may know exactly where it is, but it needs a mobile signal to send that location to you. Severe storms can knock out power to phone masts or damage network equipment in some areas.
If that happens, many trackers store location data and send it once the connection returns, so you may see a delay rather than a complete loss of tracking. Trackers that can switch between networks are generally better placed to cope with local outages.
Water Damage and Flooding
Most vehicle trackers are built to handle the conditions inside a car. Portable units used on motorbikes, trailers, plant or boats need proper water resistance. Check the device’s IP rating before fitting it anywhere exposed to rain or spray.
If your vehicle is caught in a flood, the tracker may stop working along with the rest of the car’s electrics. A tracker with a backup battery gives you the best chance of locating the vehicle afterwards.
Do Solar Storms Affect GPS Trackers?
Space weather is different from the weather outside your window. Strong geomagnetic storms caused by the sun can disturb the upper atmosphere that GPS signals travel through, which can reduce accuracy or cause temporary disruption.
Major solar storms are uncommon, and the UK is usually only affected by the most extreme events. Even then, trackers tend to keep working with slightly reduced accuracy rather than failing completely. The Met Office monitors space weather around the clock and issues warnings when a significant storm is expected.
Tips to Keep Your Tracker Working in Any Weather
• Choose a hardwired tracker with a backup battery for your main vehicle
• Have hardwired units fitted by a professional installer, out of reach of the elements
• Check portable tracker batteries more often in winter
• Clear snow and ice from externally mounted units
• Pick devices with a suitable IP rating for exposed use
• Turn on tamper, power loss and low-battery alerts
• Check the app after a major storm to confirm your tracker is reporting normally
Frequently Asked Questions
Does heavy rain stop a GPS tracker from working?
No. Heavy rain can weaken GPS signals very slightly, but not enough to stop a vehicle tracker from finding its location.
Can a tracker lose signal in a storm?
The GPS side rarely drops out because of weather. If location updates stop during a storm, a local mobile network outage is the more likely cause. Many trackers store data and send it once the signal returns.
Do GPS trackers work in snow?
Yes. Hardwired trackers inside the vehicle are unaffected. Portable units mounted outside may lose some accuracy if they are covered by thick snow or ice.
Does cold weather drain a tracker’s battery?
Cold temperatures reduce battery performance, so portable trackers may need charging more often in winter. Hardwired trackers draw power from the vehicle and often include a backup battery.
Can solar storms affect my car tracker?
Very strong solar storms can reduce GPS accuracy for a short time. These events are rare, and trackers usually keep working with slightly lower accuracy.
The Bottom Line
Bad weather is not a reason to worry about your tracker. GPS works through rain, fog and storms, and most issues come down to battery health, network coverage or how the device is fitted. For year-round reliability, choose a professionally installed, hardwired system with a backup battery.
