The hardest hit region was Leiria, with 20,348 hectares, about 16 percent of the total.
The Leiria region was affected by the great fires at Pedrógão Grande, where more than 60 people lost their lives and 20,072 hectares of forest was burnt down.
Almost 79 percent of mainland Portugal was in severe or extreme drought in July, the weather agency said recently.
In related news, Alentejo farmers and vets have donated tons of animal feed to Pedrógão Grande fire victims.
Farmers and vets in the Alentejo have collected 14.5 tons of animal feed to help feed the animals affected by the massive fire in Pedrógão Grande last month.
Among the donations are tons of grain for chickens, and food for small farm animals such as pigs, goats and sheep.
At least 64 people died in the fire which broke out in Pedrógão Grande on 17 June, and also killed hundreds of animals and took a week to put out.
