1 appliance and a water carrier were mobilised to the scene on Hallets Shute after calls from concerned members of the public.
The fire is said to have been creating smoke and ash, which was blowing towards thatched roof homes.
The crews used main jets to dowse the bonfire.
A spokesperson has said:
“Please stay home to help save lives and please don’t light huge bonfires and leave them unattended because we want to stay home too as much as possible!”
