As temperatures hit 48 degrees Celsius in parts of the Algeria, it recorded 97 blazes across 16 provinces, fanned by strong winds, said the interior ministry of the country, reports AFP.
The fires killed at least 34 people, including 10 soldiers, as they raged through residential areas, the interior ministry said, revising an earlier toll of 15 dead.
According to that initial toll, at least 26 people were also injured.
Some 1,500 people were evacuated from the Bejaia, Bouira and Jijel provinces east of the capital Algiers, according to the ministry.
The three provinces in Algeria's Mediterranean coastal region have seen the worst of the fires.
President Abdelmadjid Tebboune on Monday expressed his condolences to the families of the deceased.
The interior ministry said that 7,500 firefighters and 350 firetrucks were mobilised with aerial support to fight the flames.
Operations were underway to extinguish fires in six provinces, it added, calling on citizens to "avoid areas affected by the fires" and to report new blazes on toll-free phone numbers.
The Bejaia prosecutor's office has ordered a preliminary probe to identify the causes of the blazes and potential perpetrators, it said in a statement.
Images shared by local media showed fields and forests that had caught fire in the area as well as charred vehicles and storefronts destroyed by the flames.
In the northeastern province of Tizi Ouzou, 15 fires were extinguished late Sunday, according to civil protection forces.
Fires regularly rage through forests and fields in Algeria in summer, and this year have been exacerbated by a heatwave that has seen several Mediterranean countries break temperature records.
