Emergency services across Britain are trying to put out loads of fires brought on by the hot weather. There have been 1000 gorse-fires in Northern Ireland alone.
About 60 firefighters have been tackling a massive moor fire in West Yorkshire. April 2011 was the hottest on record, and there's only been half the normal amount of rain.
These firefighters are trying to control blazes in Swinley Forest near Crowthorne in England. Lots of families have had to leave their homes.
Strong winds have caused the blazes to spread fast. This is the scene after an area of the Swinley Forest was put out.
These heath fires have been blazing in Kintail, Scotland. They've spread through an area where lots of new trees have just been planted.
Environmentalists are really worried about the plants and wildlife which have been affected by the fires.
Police are investigating whether any of the fires were started on purpose. Some firefighters have seen teenagers running from fires and think they might've started them off.
