- Temperatures are likely to rise in parts of Punjab, Sindh and Balochistan.
- The Met Office advises the public to avoid unnecessary sun exposure.
- The upper parts of the country are likely to experience colder conditions.
The Pakistan Meteorological Department (PMD) on Monday issued a heatwave alert, warning of a significant rise in temperatures in some parts of the country in the coming days.
Mild heatwave conditions are expected to develop in the south of the country from April 29 to May 3, the Met Office said in an advisory.
According to the PMD, the conditions of the El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) remain neutral; however, most flat areas are likely to experience extreme heat.
There is a 61% chance of El Niño conditions emerging during the May to July period, which could influence regional weather patterns.
In the coming days, temperatures are expected to rise in southern Punjab, Upper Sindh and Balochistan.
The Met Office said mercury levels may remain four to six degrees Celsius above normal, and temperatures in flat areas will likely reach between 43 and 45 degrees Celsius.
He advised the population to avoid unnecessary sun exposure, especially during peak hours.
Health experts warned that heat wave conditions could increase health risks, especially for the elderly, children and patients, and urged precautionary measures.
Meanwhile, the upper parts of the country are expected to experience relatively colder conditions due to the influence of western weather systems.
These systems are likely to affect the region from the night of April 27 to 29, and again from May 3 to 5, causing a temperature drop of two to four degrees Celsius during these periods.
However, officials warned that heat intensity is likely to increase again after May 1, and intermittent heat wave conditions are expected to persist.
Climatological data shows that May and June are typically the hottest months in Pakistan, particularly in southern Punjab, upper Sindh, and southern and eastern Balochistan.
Temperatures in these regions often rise to extreme levels, occasionally reaching up to 52 degrees Celsius during intense heat wave episodes, while the normal range remains between 43 degrees Celsius and 45 degrees Celsius.
According to recent observations, temperatures in these heat-prone areas are currently two to four degrees Celsius above normal.
