The best time to visit Kõrgessaare is during the summer months, from June to August, when the weather is warm and pleasant, and the days are long.
During this period, temperatures are typically mild, ranging from 18°C to 22°C (64°F to 72°F), making it ideal for outdoor activities like exploring the coastline, cycling, and hiking in the nearby nature reserves. The long daylight hours, often extending past 10 PM, provide ample time to enjoy the natural beauty of the island. This is also when most local services and attractions are fully operational.
For those looking for a quieter experience with fewer crowds, late May and early September can also be good options.
