July and August are the hottest months, frequently reaching 35°C or more, with occasional heatwaves above 38°C.

Winters (December–February) are mild, with average highs of 15–17°C and lows of 3–5°C. Snow is extremely rare, and cold snaps are usually brief. Days are shorter, with 5–6 hours of sunshine, but outdoor activities remain popular thanks to temperate conditions. Spring (March–May) and autumn (September–November) are the most pleasant seasons, with highs of 22–29°C, lows of 10–19°C, and moderate rainfall.
