Karachi’s climate is shaped by its coastal location and subtropical latitude. Summers (April–October) are long, hot, and humid, with average highs of 33–36°C and nighttime lows around 26–29°C. May and June are typically the hottest months, with temperatures sometimes exceeding 40°C. Sea breezes from the Arabian Sea provide some relief, but humidity remains high, making the heat feel more intense. The monsoon season arrives from late June to September, bringing most of the city’s annual rainfall – up to 80–100 mm in July and August – though total yearly precipitation is modest (200–300 mm). Monsoon rains can be heavy and brief, sometimes causing flooding, but many days remain sunny or partly cloudy.
Winters (December–February) are mild and dry, with average highs of 24–28°C and lows of 12–17°C. January is the coolest month, occasionally dropping below 10°C at night during cold spells, but frost is extremely rare. Humidity is lowest in winter, and skies are typically clear, making this the most comfortable time for outdoor activities. Spring (March–April) and autumn (October–November) are short and transitional, with rapidly rising or falling temperatures. Karachi enjoys about 3,000 hours of sunshine annually, with daylight ranging from 10 hours in winter to 14 hours in midsummer. Winds are generally moderate (10–22 km/h), with brisker sea breezes in summer and drier northeasterly winds in winter. The city’s arid landscape and proximity to the Arabian Sea create a unique blend of maritime and desert influences.
