You can apply right now from what I remember! Congratulations!
I came through clearing two years ago, I remember what a relief it is to find somewhere xD
All first years are guaranteed accommodation, clearing or not- however, some of the halls may now be full. Your best bet would be to check out the accommodation website
https://www.bangor.ac.uk/itservices/admin/halls/applicants.php.en. I know it says the expiry date is in like, July, but it still works- Clearing Applicants can still apply
More information about the halls can be found here:
