The best advice we can give is to attend an organised event rather than risking your safety by having your own bonfire or fireworks display.
Here are a list of organised displays that firefighters are involved with in North Wales:
Mold - Tuesday 5th November at Mold Alex Football club at 6.30pm. £3 adults and £2 for under 16.
Rhyl - Tuesday 5th November at The Showfield at 7.30pm
Buckley - Tuesday 5th November Higher Common, Hawkesbury Road at 6pm. Free admission.
Amlwch - Friday 1st November at Madyn Field at 6.30pm. £3 adults and free for under 16..
