Thunderstorms can be an impressive natural spectacle, but pose a serious danger when camping. Regardless of whether you are travelling in a tent or a motorhome: The right preparation and knowledge of safety measures are crucial for surviving thunderstorm days safely and comfortably. This article offers you practical tips on how to prepare for stormy weather.
Preparation is the key: weather forecasts and site selection
Always keep an eye on the weather
The most important rule when camping in thunderstorms is to be informed in good time. Use reliable weather apps and local radio or weather services to check forecasts for the next 24 to 48 hours. Pay particular attention to warnings of heavy rain, hail and squalls. Plan your activities so that you reach a safe shelter in good time before the storm.
The secure parking space
The choice of parking space often determines safety. Avoid the following locations if there is a risk of thunderstorms:
- Under individual, tall trees (risk of lightning strikes).
- On hilltops or open fields (highest risk of lightning).
- Near rivers or in depressions (risk of high water and flooding).
A well-protected campsite, ideally surrounded by low vegetation or close to permanent buildings, is the best choice.
Safety measures for tent campers and motorhome enthusiasts
Protection in a motorhome or caravan
Thanks to their metal bodywork, motorhomes and caravans offer excellent protection based on the Faraday cage principle. In the event of a direct lightning strike, the current is dissipated via the outer shell. Nevertheless, you should observe a few rules:
- Disconnect all external connections (power cables, TV aerials) to prevent damage caused by overvoltage.
- During a thunderstorm, do not touch any metal parts in the interior that are in direct contact with the outer wall.
- Keep windows and skylights closed to prevent water ingress and wind damage.
Safety in the tent
Tents do not offer lightning protection. In the event of a thunderstorm warning, tent campers must act quickly. Immediately seek shelter in a permanent building, a sanitary building, a car (which also serves as a Faraday cage) or, if nothing else is available, in a deep hollow away from trees.
If you are unable to leave the tent, avoid touching the tent poles or the outer skin. Squat on an insulating mat and keep your feet together. This minimises the risk of a tingling current (step voltage).
Dealing with storm damage and heavy rain
Storm protection for the equipment
Wind is often more dangerous than lightning. Secure tents and awnings with additional guy ropes and robust pegs. Stow away loose objects such as chairs, tables and barbecues that could become dangerous projectiles. Be sure to fold up awnings and sun sails, as these can easily tear off in strong gusts.
Water management
Heavy rain can quickly flood the campsite. Make sure that your tent or motorhome is not pitched in a depression. If necessary, dig small drainage ditches around the tent to drain off the water. Check the tightness of windows and roof hatches.
What you should know
Thunderstorm camping requires respect for nature and good planning. Inform yourself, choose a safe location and make sure your equipment is storm-proof. In an emergency, the safety of people always takes top priority. A storm that is well weathered can be an exciting but safe experience.
