Sindh is Pakistan's southeastern coastal province, anchored by the sprawling port megacity of Karachi and stretching north along the Indus River to the ancient ruins of Mohenjo-daro. The province blends a major commercial capital with Sufi shrine culture, desert landscapes in the Tharparkar region, and some of South Asia's most significant archaeological and funerary sites, including the UNESCO-listed Makli Necropolis near Thatta.
Sindh spans a coastal-to-desert climate gradient along the Indus River and the Arabian Sea. Karachi, on the coast, has a hot desert climate moderated by sea breezes, with relatively mild winters (highs around 25-27C) and a long, humid pre-monsoon and monsoon stretch from April through September; it rarely gets as extreme as interior Sindh because the sea keeps the swings narrower. Interior Sindh, including Sukkur, Larkana, and Jacobabad, has a true continental hot desert climate with none of Karachi's coastal relief: summer daytime temperatures regularly exceed 45C, and Jacobabad has recorded some of the highest surface temperatures ever measured on Earth. The July-August monsoon brings the bulk of Sindh's modest annual rainfall province-wide, occasionally causing serious urban flooding in Karachi and riverine flooding along the Indus. Winter (November-February) is by far Sindh's most comfortable season across the entire province, with mild days and cool nights, and is considered the best time to visit.

The seasons
What to expect in each part of the year.
Spring
Months: Mid-Feb to Apr
A short transitional season as winter's mild temperatures give way to rising heat; by April, interior Sindh is already approaching summer-like highs while Karachi remains comparatively temperate a little longer thanks to the sea breeze.
Summer
Months: Apr-Jun
Intense heat builds through the period, with interior Sindh (Sukkur, Larkana, Jacobabad) regularly exceeding 45C and occasionally pushing past 50C in the hottest spells; Karachi is somewhat more bearable due to sea breezes but still sees high heat and rising humidity by June ahead of the monsoon.
Monsoon
Months: Jul-Sep
Karachi and coastal Sindh see periodic, sometimes very heavy monsoon downpours that have caused serious urban flooding in past years, while interior Sindh receives less rainfall but stays hot and humid; heavy monsoons can also raise Indus River levels, affecting travel near riverside sites.
Autumn
Months: Oct-Nov
Temperatures ease from the summer and monsoon peak, with October still warm but October evenings and November days becoming genuinely comfortable across most of the province.
Winter
Months: Dec-Feb
Sindh's most pleasant season by a wide margin: Karachi sees mild days around 25C and cool nights, while interior Sindh has warm, dry days and notably cool, sometimes chilly nights given the desert's lack of humidity to retain heat.
