At the weekend, extremely cold air crossed equator and in some parts of northern DR Congo, anomalously low maximum temperatures only slightly above +20°C are estimated to reach, regionally.
From very to extremely cold air hit parts of Cameron, Congo, Uganda, western Kenya, Ethiopia or even Angola, Zambia, Tanzania during last hours.
In hotter, southern regions, maximum temperatures dropped below +30°C and extremely hot summer was interrupted.
Moreover, cyclone Guambe is expected to hit Mozambique and South Africa during the weekend and early next week, what is bringing additional cooldown into southern parts of Africa.
Similar event happened in Summer 2020, when extreme coldwave hit Brazil and extremely cold air shifted later above Colombia. In southern Colombia this time was measured maximum temperature only around +20°C /https://mkweather.com/2020/08/23/antarctic-air-has-crossed-the-equator-in-southern-colombia-temperatures-dropped-from-36c-97f-to-14c-57f// thanks to Antarctic blast.
