Perihelion normally comes o n 4th January every year.

Because of Earth's tilt, sunlight strikes the southern hemisphere at a 90-degree angle.

Because the Earth and the Sun are closer together at perihelion, the sun's rays are concentrated more heavily on the surface of the planet.

Elena Antonova

At perihelion, the point in its orbit where it is closest to the sun, the sun's rays are concentrated most intensely on the region of Earth that is directly facing the sun. This concentration of sunlight occurs because Earth is closest to the sun at this point in its orbit, resulting in a more direct angle of incidence for the sun's rays. As a result, the sunlight that reaches Earth at perihelion is more concentrated and can have a greater impact in terms of heating and illumination compared to other times of the year.
