The angle at which sunlight strikes the earth, which varies by location, time of day, and season, is an important factor in the amount of energy received at any location on the globe. Seasonal change in the angle of sunlight, caused by the tilt of the earth's axis, is the basic mechanism that results in warmer weather in summer than in winter.

• As you can see in the attached figure: 
  In june, the angle at which the sunrays strike Earth is steeper around Egypt and shallower around South Africa => it will be warmer in Egypt;
  In January, the angle at which the sunrays strike Earth is steeper around South Africa and shallower around Egypt => it will be warmer in South Africa.

Note: This question is seen as a ‘drop down’ question in UK CAA with two boxes, and the choices being ‘warmer/colder’.
