There are about 60 firefighters at a massive moor fire near Mytholmroyd in West Yorkshire and in North Yorkshire a fire is threatening an industrial estate on the outskirts of Thirsk.
Nine crews are at a fire near Belmont, near Bolton in Lancashire, and two engines are at another moor fire near Ormskirk. A Lancashire Fire and Rescue Service spokesman said: "We are hoping it rains, as the land is so dry."
A large area of heather and gorse was on fire on the Balmoral Estate, the Royal Family's home in Scotland.
Fires in the wild can be caused by sunlight shining through bottles or glass and causing a spark or by cigarettes that aren't put out properly.
