The best time to go to Balatonkeresztúr is during the summer months, particularly from June to August, when the weather is ideal for enjoying Lake Balaton.During July and August, the average daytime temperatures are around 27-28°C, superb for swimming, sunbathing, and water sports on the lake. The lake water itself warms up considerably, averaging 24-26°C, making it very pleasant for a dip. This peak season also sees all the local amenities, restaurants, and attractions fully operational, offering the widest range of activities and services.For those who prefer slightly milder weather and fewer crowds, late May and early June, or September, can also be good options. The temperatures are still pleasant, usually in the low 20s, and the lake is still warm enough for swimming, especially in early September.
