JOHANNESBURG (Reuters) - South Africa's financial hub Johannesburg hit a record temperature of 38 degrees Celsius on Thursday, the South African Weather Service said, as a drought persisted in Africa's largest producer of maize.
The previous record of 36.5 degrees Celsius was recorded in November 2015, the weather service said.
Temperatures in the capital Pretoria scaled a new high of 42.5 degrees Celsius, from a previous record of 41, with the latest rolling heat wave to scorch South Africa expected to last until Friday.
South Africa may need to import as much as 5 million tonnes of maize this year, roughly half of its requirements, because of its worst drought in three decades, the country's largest producer group said on Wednesday.
