Based on the Malaysian Meteorological Department, schools in Malaysia are allowed to close, if they experience a heat wave of 37 degrees for 3 consecutive days.
The decision was announced by the MOE, and was done due to harsh weather conditions at certain locations around the country.
According to the Star, the average temperature throughout most of Malaysia has been forecasted to be at about 35°C from late April to early May.
In addition, some parts of the country have already recorded temperatures above 36°C.
The system is of two-tier. For the first level, should temperatures range from 35°C to 37°C for three consecutive days, schools must suspend all outdoor activities for students and teachers.
This includes camping, marching, outdoor sports and games, as well as agricultural activities.
In Kelantan, two children have passed from the heat, one aged 19 months, and another aged 11. Government officials have begun the discussion of extending school holidays.
Previously, the country closed about 259 schools in Apr 2016, in Perlis and Pahang, when temperatures exceeded 37°C over a period of three days.
