Karlovci doesn't depend on the season the way a beach or a ski resort does — the cathedral, the Gymnasium and the chapel stand there all year. What changes is September: that's when the Karlovci grape harvest falls, and cellars that otherwise need a call ahead run a full tasting programme.
Month by month
Average of the daily mean, 2021–2024 — not a daily maximum or minimum
The grape harvest is a fixed September weekend
The Karlovci grape harvest in 2026 runs from 11 to 13 September — three days when the centre works differently from the rest of the year, with stalls and tastings that don't need a call ahead the way the rest of the year does. Anyone coming those days should plan around the crowds, not just the festival.

The rest of the year works, but by appointment
The cathedral, the Gymnasium from outside, the fountain and the chapel are open all year, with no season that closes them. Only a cellar tasting outside the harvest always needs arranging ahead — Karlovci isn't a place where you walk into a cellar unannounced.
