The climate of Kashan
Nestled in the Iranian landscape, Kashan experiences a distinctly arid, mid-latitude steppe climate, as classified by the Koppen climate system under the category BSk. This classification hints at the dryness the region faces, given the infrequent and limited rainfall, specifically ranging from a peak of 34mm (1.34") in December and January, dipping drastically to a near absence at 0mm (0") to 2mm (0.08") from June to September.
Within this austere environment, the weather demonstrates marked fluctuation. Notably, temperatures take a biting dip in the colder months, reaching lows of -2°C (28.4°F) in January, only to steadily climb, hitting a peak at a sweltering 40°C (104°F) in July. Alongside this, daylight hours fluctuate considerably, oscillating between a peak of 14.4 hours in June and decreasing to a short 9.9 hours in December. The changing daylight conditions are mirrored in a similar rise and fall in sunshine hours, which range from a peak of 11 hours in June and July and tapering off to 6 hours during the winter months.
Intriguingly, despite being situated in a largely arid region, noteworthy occurrences in rainfall patterns appear. Remarkably, December and January have the highest rainfall occurrence at 34mm (1.34") across 8 days each month, presenting an anomalous increase within the pervasive dry conditions.
