The best time to go to Birstonas is during the warmer months, specifically from late spring (May) through early autumn (September).This period offers pleasant weather, superb for enjoying Birstonas's natural beauty and outdoor activities. The average temperatures are comfortable, ranging from 15°C to 25°C, making it ideal for exploring the Nemunas Loops Regional Park, cycling along the river, or relaxing by the water. You'll find most of the town's cafes, restaurants, and spa facilities operating at their fullest during these months.For those looking for a relaxing and rejuvenating spa break, the summer months (June to August) are particularly suitable. The longer daylight hours and warmer temperatures enhance the experience of the outdoor mineral water pools and walking trails. It's also a good time for couples seeking a peaceful getaway, as the town is bustling enough to feel lively but still maintains a calm, uncrowded atmosphere.If you prefer slightly milder weather and fewer visitors, late spring (May) and early autumn (September) are excellent choices. The landscape is beautiful with spring blossoms or autumn colours, and you can still enjoy most outdoor activities without the peak summer crowds.
