This isn’t about keeping dry in your tent when it’s raining, this is about avoiding those mornings when you awake to find the inside of your tent covered with little droplets of water. If you’ve every experienced this phenoma, then you know that even the slightest brush against your tent wall will soon have you damp and wet.
To avoid condensation dripping on you in the mornings you need to vent your tent. The best way to do this is to get a chimney effect going by opening a vent down by your feet, so cool air comes in low, and opening a vent near your head, preferably towards the top of the tent. This way the heat escapes, and along with it, all that moisture.
To help with the chimney effect, it is also good idea to have your tent oriented with the vents toward any breeze or air flow going through your camping site.
