July - September
The high season is in full swing by the month of July, as tourists arrive en masse from all over the world and Hungarians take their semi-annual vacations. Lots of sunshine translates to fun outdoor activities to be enjoyed by all, from sports to open-air festivals.
July and August are the warmest months of the year in Hungary. Most of the country warms to the upper 70s and low 80s, with cooler temperatures around Lake Balaton and warmer temperatures in the east of the country, in places like Debrecen and Szeged. Lows during this time are usually in the upper 50s (Debrecen and Szeged) or the low-to-mid 60s (Budapest, Lake Balaton). By September, temperatures start their retreat, but are still very warm. Expect highs in the low-to-mid 70s, with lows between 50 and 55. By September, Hungary reaches the second of its two `dry seasons`, with as few as five precipitation days per month on average.
