Summer equinox northern hemisphere12/10/2023 Usually, the hottest day of the year is in July or August. The summer solstice is not necessarily the hottest day of the year. This means that the southern hemisphere will be celebrating its winter solstice at the same time as our summer event and vice versa.īecause it is related to tilt and not orbit distance, the Earth is actually closest to the Sun (the perihelion) in January and furthest from it (the aphelion) in July. On 21 June, the northern hemisphere is tilted at its closest point towards the sun and the southern hemisphere is tilted its furthest away from the Sun, which is why the northern and southern hemispheres have opposite seasons to one another. The Earth’s axis has a tilt of around 24°, relative to its orbit around the Sun. "At the same time, the South Pole of the Earth is pointing away from the Sun, and so the southern hemisphere has their winter solstice on the same day." "The summer solstice occurs for the northern hemisphere when the Earth moves into such a position that its North Pole is pointing in the direction of the Sun, making the Sun high in the sky," says Baskill. Essentially, it marks the point when the Sun’s rays hit this part of the Earth most directly. The summer solstice takes place at the exact moment the Sun reaches its highest point in the sky, which is when the northern hemisphere is tilted most towards the Sun. "This slight difference is caused by the Earth orbiting the Sun not in a circle, but in a slight ellipse." What is the summer solstice?
