Weather Tidbits: Summer Seasonal Lag

We discuss the 2nd part of seasonal lag in this Weather Tidbits, but focusing just on summer. While June has the summer solstice and maximum solar radiation, its actually July that has the hottest month. This happens because of the increased incoming energy from the sun balancing the re-decreasing outgoing energy of the earth. Also, the Earth’s hottest temperature occur in July over January, despite the planet being at its farthest point from the sun. The reason is because the Northern Hemisphere has more land which absorbs more heat during its summer. Compare this to the Southern Hemisphere which is covered more by water; that helps moderate temperatures, despite being closer to the sun in January during their summer.
