Any room that has a fireplace is a good room to be in when it's rainy and wet outside! Light a fire in the bedroom and spend time with your lover or light one in the family room and get out the board games.
A sleeping porch is the ideal room to spend the night in when it's raining out. If you've got a room like this then consider yourself lucky. You can stay inside and cozy up while watching the rainstorm outside. You're close to nature but comfortable inside your own home.
Not everyone has a sleeping porch but everyone certainly has a kitchen. The kitchen is a really great space for gathering together with the whole family when it rains. Heat up some hot chocolate. Cook a warm stew. Enjoy the weather together from indoors.
Do you have a music room in your house? If you've got a piano or even just a place where everyone could play some handheld instruments then the rainy months are definitely the time to gather together in this space. You all want to be indoors anyway so enjoy this time together to make some music.
The media room in your house is a good place to while away the rainy hours. Whether you've got a small TV in the living room or an entire space dedicated to the home's entertainment, this is a good coming-together spot for the whole family. Get out some favorite old movies or hot new Wii games and spend some quality time together away from the rain.
Your studio or home office is a good place to spend a rainy day. Get some work done or complete some projects. These are exactly the kind of tasks that we often leave until rainy days come along!
An outdoor room can be a good place to spend some time if it's designed correctly. These are rooms where there is open air for you to enjoy but there is enough cover for you not to get wet in the rain. You can make some minor accommodations to the roof and walls of your existing porch to create a room like this.
Any room with a view is a good room for you to be in when it's raining outside. Grab your mug of coffee and gaze out the window at the storm as it passes by.
I don't know about you but my very favorite place to be when it's rainy and gross outside is right at home in my very own bed. I want to be there with my laptop or a book or someone I love. It's the best room in the house during a rainstorm!
