Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. These places remain warm year-round. As the Earth revolves around the Sun, it gets positioned such that the Sun is directly over the equator. Basically, the Sun's energy is in balance between the northern and southern hemispheres. The same holds true on the spring equinox near March 21st, as the Sun is once again directly over the equator. On and near the equator, sunlight comes from almost directly above every day all year round; the equator therefore has a stable, daytime temperature the whole year. On and near the equator, sunlight comes from almost directly above every day all year round; the equator therefore has a stable, daytime temperature the whole year. Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. These places remain warm year-round. Near the Equator, regions typically have alternating rainy and dry seasons. Equatorial regions experience only small seasonal changes in temperature due to the relatively constant angle between these regions and the sun. The figure on the right shows how seasons are determined by the tilt of the earth's rotational axis and the orbit of the earth around the sun.
On and near the equator, sunlight comes from almost directly above every day all year round, the equator therefore has a stable, daytime temperature the whole year. The earth is tilted on its axis by 23.5 degrees on its axis, therefore the poles receives the slanting rays of the sun, but the equator receives the same amount of sunlight directly and in concentrated manner, therefore the temperatures remains same throughout the year. This axial tilt means that during the Earth's journey around the sun the poles receive varying amounts of sunlight. The equator, however, receives relatively consistent sunlight all year. The consistency of energy means the equator's temperature stays relatively constant all year. The temperature and climate in the tropics near the equator are very much the same throughout the year. The temperatures and climate closer to the poles have larger changes between summer and winter. Earth's axis always points in the same direction. Because of this, the part of Earth that receives the most direct rays from the Sun changes as the Earth travels around the Sun. At the equinox, the Sun's rays shine most directly on the equator, and the Northern and Southern Hemispheres get the same amount of Sunlight. At the equator, there are no seasons because each day the Sun falls at the same angle and everyday it receives 12 hours of sunlight. The poles remain cool because they are never tilted in the path of sunlight.
Twice a year, during the spring and autumn equinoxes, the sun passes directly over the Equator. Even during the rest of the year, equatorial regions often experience a hot climate with little seasonal variation. As a result, many equatorial cultures recognize two seasons wet and dry. At the equator, the sun is directly overhead at noon on these two equinoxes. The "nearly" equal hours of day and night are due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon when the actual position of the sun is below the horizon. Except at the equator, the equinoxes are the only dates with equal daylight and dark. At the equator, all days of the year have the same number of hours of light and dark. Between the two tropics zones, which include the equator, the sun is directly overhead twice per year. Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. These places remain warm year-round. Near the Equator, regions typically have alternating rainy and dry seasons. It happens because of the Earth's orbit around the Sun. The equator receives less direct sunlight during the year. The equator receives about the same amount of direct sunlight all year long.Although the daytime length at the Equator remains 12 hours in all seasons, the duration at all other latitudes varies with the seasons. During the winter, daytime lasts shorter than 12 hours; during the summer, it lasts longer than 12 hours. The reason for this is because Earth is tilted 23.5 degrees away from its axis of rotation. If there were no tilt, everywhere on Earth would receive 12 hours of daylight and 12 hours of night every day, regardless of how close or far to the Equator.An equinox occurs as the plane of the Earth's equator intersects the angular centre of the Sun's disc. This happens twice a year, on the 20th of March and the 23rd of September. The June solstice marks the longest day north of the equator and the shortest day in the south.
