August continues high season with warm weather and busy resorts, especially along coasts and at lakes. Some small towns observe local holiday periods, which can affect services. Outdoor sightseeing is best in the mornings and evenings during hot spells.

Average temperature across Eastern Europe in August.
Estonia, Latvia & Lithuania
Early autumn brings a crispness to the mornings, with leaves changing quickly in parks and forests across Lithuania and Latvia; daytime highs often fall back to 12-18°C. The tourist pace eases, ferry timetables become less frequent and mushroom-foraging season begins in the countryside. This is a great time for road trips and fewer crowds; bring a warm jacket and sturdy shoes for forest walks.
Poland & Belarus
Autumn brings crisp mornings and rapidly cooling days, with foliage turning in the Białowieża Forest and along river valleys. September can still be mild and pleasant for walking the canals of Gdańsk or exploring the countryside, but by October temperatures often fall into single digits and rain increases. Pack warmer layers, a waterproof and sturdy shoes for leaf-slick paths.
southern Poland, Slovakia, western Ukraine & Romania
Early autumn turns the highlands into strong autumn colour displays by September and October, with crisp air and increasingly stable weather for long ridge walks. Daytime temperatures are comfortable but mornings can be frosty at altitude; mushroom and berry season peaks in September. This is a preferred time for photographers and hikers - pack warm layers, a rain layer and durable boots for changing ground conditions.
central & eastern Ukraine, Moldova
Early autumn brings pleasant low-humidity days and comfortable temperatures ideal for city touring and vineyard tastings in Moldova; September often feels like an extended summer with highs in the low twenties. Leaf colour starts to appear in October further north and the steppe takes on golden tones. Bring a warm layer for evenings and a rain jacket for occasional frontal systems.
Romania, Bulgaria & southern Ukraine
Early autumn keeps pleasant conditions with long, mild days and sea temperatures still comfortable for swimming through September and into early October. Vine harvests and wine festivals in Dobruja and Romanian plains add cultural interest, and tourist crowds thin. A light sweater for evening strolls and shoes for countryside walks will keep you comfortable.
St. Petersburg, Moscow & surrounding regions
Early autumn is crisp and picturesque as trees turn russet and gold; daytime highs typically fall into the 10-18°C range, and many cultural events restart after the summer break. St. Petersburg and Moscow offer comfortable walking weather for museums and historic districts; evenings will be noticeably cooler. A warm jacket, scarf and waterproof shoes are practical for comfortable city touring.
