To allow the air to circulate
The sides of a Stevenson screen are louvered to allow air to circulate freely around the temperature and humidity sensors inside. This design helps prevent the sun's direct rays from hitting the sensors and affecting the accuracy of the readings. The louvered sides also help to reduce the impact of thermal radiation on the inside of the screen.
