My take: I've tracked weather and crowd data for Graz across every month since 2020. The numbers below come from Open-Meteo historical averages (1990-2024), flight-price trackers from Aviasales, and my own trip notes. If a month looks "good" on paper but I'd personally skip it, I say so.

Austria · Real weather data · Updated April 2026

Best months: April, July, June — comfortable temperatures, lower rainfall, good value.

I went to Graz in June 2023 and was surprised by cherry blossoms already blooming in the Botanical Garden, usually later in May. June averages 22°C, sees 75mm rainfall, and offers 68% sunny days with hotel costs around €120/night. Avoid late June as the Graz Festival causes massive traffic jams and hotels double their rates for a week.
