How to Keep Your Outdoor Extension Cords Dry?

Spring days mean finally being able to use your backyard and enjoy longer days. With that comes a little bit of rain, and you need to protect your electrical connections for outdoor lights and such. Let’s see some DIY tricks to see how to ensure your outdoor lights can weather any storm!

The Rainy Day Blues:

The thrill of twinkling lights can quickly turn into a damp dud if they succumb to the elements. Extension cords, the lifeblood of outdoor decor, become vulnerable targets for rain and moisture. But before you pack away your party plans, we have some tips to show you how to protect outdoor extension cords from rain.

DIY Defense System:

  • The Plastic Protector

    • Materials:

      Grab a sturdy plastic container with a removable lid (think storage bins or even an unused ice cream tub).
    • Assembly:

      Drill holes at each end, big enough for your cords but not wide enough to let rain sneak in. Use a utility knife to widen the holes where needed. Now, simply insert the plugs, snap on the lid, and voila! Your connections are shielded from the downpours.
    • Advantages:

      Affordable, readily available, and offers ample space for multiple plugs.
    • Disadvantages:

      It may not be aesthetically pleasing and requires some crafting skills.

  • The Inner Tube Armor:

    • Materials:

      Slice off a 6-inch section of an old bicycle inner tube.
    • Defense:

      Stretch one end of the tube over the plug, then plug the tool into the outlet. Slide the other end of the tube over the exposed connection. Boom! Water-tight barrier achieved.
    • Advantages:

      Simple, readily available, and quite flexible.
    • Disadvantages:

      Limited protection for longer cords, not ideal for multiple connections.

  • The Plastic Bag Fortress:

    • Materials:

      Grab a heavy-duty plastic bag (think trash bags).
    • Shielding:

      Bundle the entire extension cord with the bag, securing it with tape or ties. You can create additional bundles for longer cords.
    • Advantages:

      Easy, inexpensive, and offers basic protection for the entire cord.
    • Disadvantages:

      Not the most aesthetically pleasing, provides minimal protection for plugs.

Commercial Crusaders:

If DIY isn't your forte, fret not! Weatherproof extension cord covers with pre-made enclosures offer peace of mind. These often feature gaskets and seals for enhanced protection.

The Dos and Don'ts of Cordonious Conduct:

  • Do: Use extension cords as temporary power sources.
  • Do: Inspect cords for damage before use.
  • Do: Fully plug them in and securely connect them to devices.
  • Do: Unplug by grasping the plug, not the cord.
  • Do: Store them safely in a dry location after use.
  • Don't overload cords with too many devices.
  • Don't use them with damaged plugs or frayed wires.
  • Don't run them through doors, windows, or under carpets.
  • Don't use them as permanent wiring solutions.


  • Can I use metal tape for my DIY cover? 

No! Metal conducts electricity, so avoid it like a rainy thunderstorm.

  • Are commercial covers better than DIY solutions? 

It depends. Commercial options offer guaranteed weatherproofing, but DIY methods can be cheaper and customizable.

  • What if my extension cord isn't long enough? 

Don't stretch it! Move the device or install a new outlet to avoid overloading and potential fire hazards.

Conquering the elements starts with knowledge and preparation. Choose your defensive strategy, follow the dos and don'ts, and let your outdoor oasis shine brightly, rain or shine. Remember, staying safe and dry is the key to enjoying the magic of outdoor lighting all season long!
