Summers are often dry across Portugal; however, most of the nation has received no rainfall so far in August.
In fact, dating back to the end of June, northern Portugal has received roughly only 10 percent of their normal precipitation.
This long stretch of dry weather, combined with unseasonable warmth and some gusty winds, has resulted in wildfires across northern and central parts of the nation.
A sixth firefighter has died from injuries suffered while battling blazes across Portugal this summer, according to the Associated Press. At least one other firefighter remains in the hospital with serious injuries.

Latest reports indicate at least 700 firefighters are actively working to control a number of fires across the region.
The fires have been so bad that Portugal began seeking aid from Spain and France to battle the blazes.
Jorge Dias, spokesman for Portugal's National Civil Protection Authority, said Friday that France and Spain have each sent three Canadair planes designed for dropping water on wildfires, but more are needed.
Croatia has sent two additional aircraft to aid in the fire fighting efforts across Portugal.

Portugal's Institute for the Conservation of Nature and Forests has said that more than 230,000 acres have burned across the country so far this year.
A change in the weather pattern will begin to unfold Wednesday night into Thursday as a trough approaches from the northwest leading to the threat of some rainfall across the northern third of Portugal.
As this trough pushes into the region temperatures will be lower each day from Thursday into the weekend. Unfortunately for the firefighters, rainfall from Friday through the weekend is expected to be generally light and isolated. Also, there can be some gusty winds which could actually help spread existing fires.
