September brings crispness to Tallinn’s parks and a thinning of the tourist crowd; daytime temperatures often fall into the low teens and the first golden leaf color appears in Kadriorg. The sea cools quickly, and mornings can be foggy along the coast, which is atmospheric but damp - bring a compact umbrella and layers. Cultural life resumes in earnest with concerts and exhibitions after summer breaks.
