Skydiving during winter?

I was wondering if there’s anyone here in Auckland that’s done skydiving in Winter at least once or multiple times, and if you have, would you advise me to not do it during Winter, or yolo and go for it?

If yes (and go for it), do you have any advice on what I should wear and be prepared for? I haven’t gone skydiving at all and I’ve been wanting to go for many years, and I really wanted to do it close to my birthday but unfortunately my birthday is during peak winter season.

Any advice or experience is appreciated thanks!! :)
