No, It seems to be working correctly… With a low temperature (12.3C/53.1F) and high humidity (86%), the CBI will be LOW (<50). That’s cool and moist, so low fire danger.

thanks for your answer Ken
the problem is the CBI I have see 1 time 14 and that was with very high temperature 30+ C
it was code oranges on that time into my country but on my script it was CBI 14 ( LOW)

The Chandler Burning Index is not widely used for ‘official’ fire danger prediction anymore as it only relies on temperature and relative humidity. It’s likely that it will not match an official pronouncement since they use much more complicated formulas and other data items (not normally available on PWS systems) to make the judgement for the fire danger.
