In the northern hemisphere, many countries consider the months of June to August as the summer months. In the US for example, summer months are expected to bring lots of sunshine which is equivalent to longer days and shorter nights. Based on scientific and weather data though, it is around June 21 when the position of the Earth is at a point where the Sun is at its most northern point. This means that June is the time when the Sun is at the top of the earth resulting to the longest day in the year. With this kind of positioning between the Earth and Sun, many people have assumed that June is the hottest month of the year when in fact August is actually hotter. From June, the temperature actually keeps rising up to July and August and this has made people wonder why August is typically hotter than June. The basic explanation for this is that there is some kind of lag time when it comes to the heat of the sun reaching the Earth’s surface. The heat given out by the sun in June is said to reach the Earth’s surface in about 4 to 6 weeks which is already August. This basically explains why August seems hotter compared to June temperatures.
By around the third week of June, the sun gradually heats up the Earth through its rays. These rays will then need to travel to the Earth’s surface in the form of heat. The radiations from the sun travel through various long wavelengths and so result to some kind of a delay in terms of absorption. With all the radiation given by the sun in June, about 4-6 weeks is needed before they actually reach the Earth’s atmosphere in the form of heat. Around this time, it is already August in people’s calendars and people can now feel the heat that has actually accumulated from several weeks before. This long way for the radiation to travel from the sun makes the temperature rise from June up to August.
