Running a Generator in the Rain and Snow Safely

September 6, 2023

A generator is a powerful tool for providing energy in times of need, especially during natural disasters when the power grid goes down. However, many wonder if their generator can handle running in adverse weather conditions like rain, snow, or storms. Let’s discuss the factors that affect generator performance during harsh weather conditions and whether or not a generator can run when you need it most.

Generator Components 

To understand if a generator can run in rain, snow, or storms, we need to understand the components that make up this powerful tool. A generator consists of an engine, alternator, fuel system, voltage regulator, and battery. All these components work together to generate and convert electricity. Still, if any of these components fail or moisture gets into any of the elements, the generator’s performance can be negatively affected.

Rain and Snow

Many generator manufacturers design their products to be weather-resistant but not necessarily waterproof. Rain and snow can affect the generator’s output and even lead to a short circuit which can cause long-lasting damage. However, if your generator is located in a covered area or if you have a generator enclosure, it can help protect your generator from moisture. Generac generators, however, are built to withstand difficult conditions—still, it’s best to take precautions. 


Storms can be unpredictable, and the amount of rain, wind, and thunder can vary from one tempest to another. This can be challenging for a generator, but it can still function if installed correctly and maintained regularly. During heavy storms, there is a higher risk of power outages, which can strain the generator. This also depends on the generator’s power output and how many appliances it needs to run.

Generator Maintenance

To ensure that your generator can withstand harsh weather conditions, it is essential to maintain it regularly. This includes regular oil changes, keeping the fuel tank full, ensuring all components work correctly, and cleaning your generator thoroughly. Regular maintenance will help your generator perform better, particularly during adverse weather conditions and when you need it most.

Generator Safety

Keeping your generator safe during harsh weather conditions is essential to avoid accidents. This includes not opening the generator during rain, snow, or storm conditions, keeping the generator away from flammable materials, and using a ground fault circuit interrupter (GFCI) to avoid electrical shocks.
