Most people experience allergies in the spring and fall but during the summer months, they go away depending on where you live. When seasonal allergies aren’t at bay, you won’t experience an allergy-induced buildup of mucus in the nose. Allergies can clog your nose and force you to snore because you can’t breathe through your nose.
During the summer, these allergies aren’t present which means your nose isn’t blocked with mucus. Therefore, you don’t snore as much!
