Hello Cruisegirlsa; we sailed from Copenhagen on June 23. The weather for the most part was beautiful; a little cool for a Southern California boy, but very enjoyable. The temps ranged from a low of 54 in St. Petersburg to a high of 68 in Stockholm. We had light rain one day in St. Petersburg and a pretty good rain for a couple of hours in Oslo. The rest of the time it was beautiful--occasionally some high, thin clouds, and always a nice light breeze. Most of the time it was in the high 50's to low 60's.
Hope this helps.
