Egypt's Meteorological Authority (EMA) said on Sunday that temperatures are expected to continue to rise in several parts of the country, with mercury climbing to 42 degrees Celsius in Cairo on Wednesday.
The temperature is expected to slightly go down gradually afterwards, the EMA added.
Greater Cairo, Lower Egypt, the North Coast, South Sinai, and the southern part of the country will see extremely hot weather from Monday to Wednesday.
Greater Cairo and Lower Egypt will see highs ranging from 39 to 42 degrees Celsius and lows ranging from 22 to 23, while Upper Egypt will see highs ranging from 41 to 43 degrees and lows ranging from 23 to 28 during the same period.
The heatwave started to hit several parts of Egypt as of Thursday.
The hot spell comes as Egyptians mark the Sham El-Nassim holiday on Monday at home amid tight precautionary measures against the coronavirus introduced by the government to prevent gatherings that may lead to the further spread of coronavirus infections.
Egyptians usually mark the Sham El-Nassim spring holiday with picnics in public spaces, which urged the municipal authorities to close parks, zoos, and beaches throughout the spring holiday to avoid gatherings.
Egypt is currently seeing a third coronavirus wave, with daily tolls recording over 1,000 since Wednesday.
