Technically there is nothing stopping you using any nighttime firework during the day. Be aware though that most of the coloured effects are likely to be lost. Still, for sound effects, any normal nighttime firework can be used. Example sounds that work well include:
Bangs: Salute/airbomb cakes work just as well during the day if you need multiple bangs. Otherwise, with airbombs long since banned in the UK you need to be looking at rockets for single bangs. It’s usually simpler here to approach your local fireworks specialist and enquire what’s available in the salute rocket range. Failing that, look for 1.3G class rockets as these pack a good punch (1.4G rockets often just “pop”).
Crackles: Many cakes and barrages are available that fire crackling comets, these work well in the day.
Whistles: Another effect that’s quite effective in daylight.
Note: Chinese crackers, bangers and airbombs are no longer legal in the UK.
