Tanning season is from mid-July to mid-September, but you can tan on the island year round. Just go out in the sun for 15 minutes or an hour or something (I've read different things) each day, and leave off the sleeves/hats as tokkio said (this guide has a list of items that will prevent tans, under "other useful lists"). Note that you can only get one shade darker each day so it might be a few days before you notice results. Hope this helps
ok thanks guy ^-^ I have found that going to the island does work
15 mins a day at the island
wearing short sleeves
no socks, shoes, hats or masks
you can go up one level of tan a day
Time traveling does work
Each day you don't tan, you go down a level.
Thx all for your help
I tested it myself and I have a nice dark tan myself
