Summers (June–August) are warm to hot, dry, and sunny, with average daytime highs of 28–31°C and nighttime lows around 17–19°C. July and August are the hottest and driest months, with as little as 7–12 mm of rain and up to 13 hours of sunshine daily. Humidity is low, and the clear skies make this the best period for sightseeing and outdoor activities. The UV index is very high, so sun protection is essential.

Rainfall is frequent, especially in December and January, with monthly totals of 90–102 mm and 11–12 rainy days per month. Snowfall is possible, particularly in January and February, and the mountain air can feel brisk. Spring (March–May) and autumn (September–November) are transitional, with mild to warm temperatures (15–25°C), moderate rainfall, and blooming wildflowers or colourful foliage. Annual precipitation averages 700–800 mm, and Delphi enjoys about 2,800–3,000 hours of sunshine per year.
