Please remember times and events can change (especially as the weather does). Always double-check event details before heading out.
After last year's cancellations, I imagine fireworks events to be extremely popular and busy this year. If you fancy a ticketed event, I would recommend booking asap.
For the purpose of this post, these events take place with 5/6 miles of Newcastle City Centre. For a more comprehensive list of displays across the whole of North East England, please check out this Fireworks Guide over on North East Family Fun.
