As the Earth travels around the Sun in its orbit, the north to south position of the Sun changes over the course of the year due to the changing orientation of the Earth’s tilted rotation axes. The dates of maximum tilt of the Earth’s equator correspond to the Summer Solstice and Winter Solstice.
What are Solstices?
Solstices occur when the sun is at its greatest distance from the equator. Solstice is derived from two Latin words: “sol” meaning sun, and “sistere” to cause to stand still. The perception that the “sun stands still” comes from the shadow on the sun dial changing minimally on and near the solstices. Solstices occur twice a year.
What is the Summer Solstice?
The Summer solstice, also called ‘Litha’, marks the first day of the season of summer. It falls on June 21.
(In the southern hemisphere, the Summer solstice is celebrated in December when the northern hemisphere celebrates the Winter solstice)
Timing in Pakistan
It is going to be the longest and could be the hottest day of the year in some cities as sunrise will take place at 5:42 am PKT while sunset will occur at 7:25 pm on the June 21, thus sunlight would shine for more than 13 hours.
So when will it start in Karachi? As the day begins at 5.42 am PKT and ends at 7.25 pm PKT. The longest day will last for 13 hrs and 43 min in Karachi. Following is the longest day of other cities;
- 14 hrs & 29 min in Islamabad, also the longest in Pakistan.
- 14 hrs & 17 min in Lahore.
- 14 hrs & 31 min in Peshawar.
- 14 hrs & 16 min in Quetta.
Other cities will also have same timing with little variations.
Bear the heat and the load-shedding!
The province of Punjab is already suffering the wrath of load-shedding, so Lahoris and Islamabadis have to face another problem that is summer solstice, they cannot even go outside in the parks due to the blazing sun. Temperatures in Islamabad could reach 44°C while 46°C to 47°C is expected in Lahore.
Usually Karachi experiences cloudy weather during the month of June but it seems like Mother Nature has decided to punish the city because there does not seem to be any cloud formation that could affect the city atleast till the daytime. Temperature in Karachi will be around 36°C – 37°C. So any plans to overcome the heat?
