In Finland, this is how Helsinki actually wears July, not how a country centroid would. July is the peak of the warm side of the year in Helsinki. If you wanted the gentlest heat, this is not that month.

What to expect
Daytime
Mild afternoons in Helsinki are the prize in July. You can eat outside on the good days. You still want something for the breeze.
This is walking weather. Shade is useful, not essential the way it is in the hot months. A long outdoor day is a reasonable plan.
Rain
July is the wet side of the year in Helsinki. Days can be heavy. Plans that cannot survive rain are the wrong plans.
This is not a reason to skip Helsinki 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
