I’m planning a trip to Greece in December and I’m wondering what the weather will be like. I’m hoping for sunny days and mild temperatures so I can take advantage of the outdoor activities that Greece has to offer. I’m curious if the weather will be warm enough for me to swim in the Mediterranean Sea or if I’ll need a jacket for cooler evenings. I’m also wondering if there will be any rain or snow during the month. Any insight into the weather in Greece in December would be greatly appreciated.
