  Hello, Camilo. If your lights flicker specifically during rainy weather, it could indicate moisture-related issues in your electrical system. Here are some common causes that we recommend to check first:

  Water leaking into electrical connections: Rainwater might be getting into outdoor outlets, lighting fixtures, or exposed wires. This can disrupt the electrical flow, causing flickering. Moisture entering these areas can also increase the risk of electrical shorts and is a fire hazard. Fixing these issues can prevent potential hazards and keep your lights flicker-free, even in rainy conditions. Calling a licensed electrician would be the best way to go. 

  Service line issues: If rain affects your power supply, there could be loose or exposed connections in your outdoor power line where it connects to your home. Utility poles and overhead lines can also be affected by rain, which impacts power flow and causes flickering.

  Faulty weatherproofing: Outdoor electrical boxes or entry points may not be properly weatherproofed, allowing moisture to get into your system. Older or poorly sealed boxes can lose their resistance to moisture, especially during heavy rainfall. You can check and update those electrical boxes by yourself. Our top recommendation is the Type 1281 Weatherproof Box.
