How to camp in the rain
Bring a waterproofed tent when you know it'll rain.
Have a tent with a rain fly that overhangs it so that rainwater drips off the sides. The tent's entrance should form a lip, like a bathtub, so the floor isn't entirely flat.
Good rain tents are also treated with waterproofing polyurethane or another product. Getting a tent with a vestibule is also helpful.
