Climate of Lahore

Definition
The climate of Lahore refers to the prevailing atmospheric conditions—including temperature, precipitation, humidity, and wind patterns—experienced in Lahore, the capital city of the Pakistani province of Punjab.

Overview
Lahore lies at approximately 31.55° N latitude and 74.35° E longitude, at an elevation of about 217 m (712 ft) above sea level. Its climate is classified under the Köppen system as a humid subtropical climate (Cwa), characterized by hot, dry summers, a monsoon season with the majority of annual rainfall, and mild, relatively dry winters. The city’s climatic regime is strongly influenced by the South Asian monsoon and by continental air masses from the north and west.

Etymology/Origin
The term “climate of Lahore” combines the English word “climate,” derived from the Greek klimatos meaning “region” or “inclination,” with “Lahore,” the name of the city. The name “Lahore” is thought to originate from the Sanskrit Lohar (meaning “black” or “metal”), though its precise historical etymology remains debated among scholars.

  • Winter (December–February): Daytime highs average around 20 °C (68 °F), while nighttime lows often fall to 5–7 °C (41–45 °F). Frost is rare but may occur on isolated mornings.

  • Winter months are comparatively dry, receiving less than 20 mm (0.8 in) per month.

• Humidity

  • Relative humidity is low during the pre‑monsoon summer (often below 30 %).
  • During the monsoon, humidity rises sharply, frequently surpassing 80 %.

• Wind

  • Prevailing winds are from the west or northwest in winter and shift to the southeast during the monsoon, bringing moist air from the Bay of Bengal.
  • Occasional dust storms occur in the pre‑monsoon period, driven by hot, dry air masses.

  • Heatwaves in late May and early June can push temperatures above 45 °C, prompting public health advisories.
  • Monsoon thunderstorms may produce localized flooding and hail.
