What to expect
Daytime
Cool days in Riga: 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
October is the wet side of the year in Riga, the wettest stretch on these averages. Days can be heavy. Plans that cannot survive rain are the wrong plans.
This is not a reason to skip Riga if you like the place. It is a reason to pack for weather and to stop treating every grey hour as a failed holiday.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
