On Monday, Islamabad is forecast to register 19°C in the morning, coldest day since summer, with a daily high near 20°C and a low near 16°C along with a chance of afternoon thunderstorms.
Morning chill arrives with cloud cover in Islamabad
Against all expectations, residents will step out to a distinctly cool start, as temperatures hover near 19°C between early morning and mid morning.
Because cloud cover limits sunshine, the air will feel cooler than recent days, and the warming through noon will be modest.
By early afternoon, readings should approach 20°C, yet the combination of cloud, humidity, and a few showers will keep conditions mild rather than warm.
Western disturbance cools the capital
Meanwhile, a western disturbance influencing northern Pakistan from October 3 to October 7 has increased cloudiness and triggered rounds of rain and thunder across upper and central regions.
This synoptic setup suppresses daytime heating and nudges morning temperatures downward, which explains today’s cooler feel.
Notably, national advisories issued at the start of the month flagged rain windstorm and thunderstorm potential during this window, consistent with the pattern now affecting the Potohar Plateau.
Consequently, short lived downpours and gusty winds remain possible later today.
Autumn context clarifies the timing
Finally, today’s 19°C morning signals an early autumn snap rather than the onset of winter.
Climate normal show that Islamabad’s October lows typically range from about 19°C at the start of the month to near 12°C by the end, while average highs ease from roughly 32°C to 27°C.
In other words, a cool morning near 19°C on October 6 fits the seasonal profile.
Moreover, last October ranked unusually warm at the national scale, so this week’s cooler turn stands out against recent years without indicating a seasonal shift to winter.
Plan for crisp mornings, a mild afternoon, and keep rain protection handy.
