The world is currently experiencing a record-breaking 12th straight month of historic heat, with this summer on track to be among the hottest yet. Heatwaves have already gripped many parts of the world, leading to over a thousand deaths, urgent health warnings, and school closures. July is historically the hottest month of the year, and this year is already on track to be one of the hottest ever recorded, according to the UN’s World Meteorological Organization.
The Earth’s axial tilt of 23.5 degrees results in varying amounts of sunlight at different times of the year, creating the changing seasons. The summer solstice marks the start of astronomical summer, with the sun reaching its highest point in the sky leading to the longest day and shortest night of the year.
In the Northern Hemisphere, where 90 percent of the world’s population resides, summer months coincide with more direct sunlight and longer daylight hours. The phenomenon of the midnight sun occurs in northernmost cities around the Arctic Circle, where the sun does not set between late May and late July.
During the summer months, the Earth’s surface absorbs more of the sun’s energy, heating up the surrounding air and leading to warmer temperatures. This seasonal lag explains why peak temperatures occur in the afternoon rather than at midday, with July typically experiencing the highest average temperatures.
As temperatures continue to soar, it’s crucial to stay cool and minimize the risk of heat stroke. Tips to beat the heat include staying hydrated, wearing lightweight and loose-fitting clothing, and avoiding strenuous outdoor activities during the hottest parts of the day. Remember to take care of yourself and others as the summer heat continues to rise.
