Weather tracker: temperatures in Spain and Brazil well above late April norm

Seville could see 34C this week and parts of Brazil could hit high 30s, while storms forecast in southern Africa

Over the course of this week, temperatures in Spain are expected to soar well above the seasonal average. Daytime temperatures could reach about 30C in Madrid on Tuesday, 10C above the norm, while Seville may experience 34C, about 9C above its late April average. An area of low pressure situated out in the Atlantic will allow for a south-westerly flow, introducing warm air from north Africa. In addition to this heat, a notable dust plume is expected to travel northwards from the Sahara, covering the skies above Iberia and south-western France, which may lead to some particularly orange or red skies at sunrise and sunset.

In Brazil, high temperatures are forecast for the states of Sao Paulo, Parana, Mato Grosso do Sul and Santa Catarina over the next few days, eventually spreading into Minas Gerais. Here, daytime maximum temperatures are expected to reach the high 30s celsius later in the week, about 5-10C above the seasonal average.
