Weather in Tallinn in May
May in Tallinn is cool outdoor weather: usable if you dress for it, not a beach brief.
In Estonia, this is how Tallinn actually wears May, not how a country centroid would. Compared with July and February, May sits in the middle of Tallinn's year.

What to expect
Daytime
Cool days in Tallinn: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.
Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.
Rain
Mixed skies in Tallinn in May. Dry days and wet days share the month. Outdoor plans need a backup, not a cancellation policy.
Pack a shell you will actually carry. The monthly table is the place for totals. This is the feel: usable, interrupted.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
