Karachi is bracing for a potential rise in temperature as the Pakistan Meteorological Department (PMD) has issued a Karachi heatwave warning for the ongoing month. Weather experts predict that temperatures will climb steadily, and the city could face extreme heat conditions by the end of April.
Temperature to Climb, Humidity to Increase
Weather analyst Jawad Memon stated that changes in wind patterns will cause daytime temperatures to rise between 36°C to 38°C. Due to high humidity, however, the “feels-like” temperature will range between 39°C and 41°C. He added that relief might arrive in the evenings as sea breeze conditions improve.
Despite a relatively stable forecast for the next 10 days, PMD spokesperson Anjum Nazir warned that Karachi could face a severe heatwave toward the end of April. He emphasized that southern parts of Pakistan, including Sindh, will likely bear the brunt of extreme heat between April 14 and 19, with temperatures soaring between 46°C and 48°C.
Water Crisis and Call for Rain Harvesting
Nazir also raised concerns about Karachi’s worsening water crisis. He pointed out that the city’s extensive concrete coverage prevents rainwater absorption, leading to wasted runoff into the sea. He urged authorities to implement rainwater harvesting strategies and dig water wells in remaining undeveloped land to replenish groundwater reserves.
The Met Office has declared moderate drought conditions in several parts of Sindh, which amplifies the urgency for effective water management.

Monsoon and Rainfall Outlook
While international weather models hint at heavy rainfall in the coming months, Nazir clarified that accurate monsoon predictions can only be made by late May or early June. So far, the winter season has recorded a significant 61% decline in average rainfall and a 50% reduction in snowfall. These shortages contribute to prolonged dry spells and worsening drought conditions.
Nazir also noted that while Pakistan will receive average rainfall from April to June—covering just 19% of the country’s water needs—regions like Khyber Pakhtunkhwa and Gilgit-Baltistan are expected to receive below-average precipitation.
Widespread Heatwave Impact Across Pakistan
The PMD had previously warned of rising temperatures across central Punjab, Islamabad, Khyber Pakhtunkhwa, Gilgit-Baltistan, and Azad Kashmir. Heatwaves in these areas could raise temperatures by 4°C to 6°C above normal.
Extreme heat conditions may also lead to dust and windstorms, posing a risk to infrastructure, including electric poles, trees, vehicles, and solar panels.
Health and Agricultural Advisories
Meanwhile, farmers are urged to plan wheat harvesting activities according to the forecast and ensure protection for their livestock.
Rising temperatures in northern regions could also accelerate snowmelt, increasing the chances of flooding in downstream areas.
As the city prepares for intensifying heat, residents are urged to take necessary precautions and remain alert to official updates.
