The best time to visit Mousthéni is during the shoulder seasons of late spring (April to early June) and early autumn (September to October).
During these periods, the weather is pleasantly warm and sunny, with average temperatures in the low to mid-20s Celsius (70s Fahrenheit), making it ideal for exploring the region's natural beauty and vineyards. You'll find fewer crowds compared to the peak summer months, allowing for a more relaxed experience at local tavernas and archaeological sites. These months also offer comfortable conditions for outdoor activities like hiking in the surrounding hills or visiting nearby beaches without the intense summer heat.
For travelers who prefer warmer weather and don't mind more activity, the summer months of July and August are also suitable. While temperatures can be higher, reaching into the high 20s or low 30s Celsius (80s-90s Fahrenheit), this is an excellent time for enjoying the coastal areas and the vibrant local festivals. Many establishments extend their operating hours during summer, offering more dining and entertainment options.
