I was wondering what is the best level should I be on before moving to Skellige. I am currently pursuing the Dandelion quest, have finished all side-quests that I came across (Secondary and Witcher contracts), excluding those that require an extremely high level.
I am at Level 14 and if my calculations are correct I should be somewhere in level 15 before I finish the main quest in Novigrad. Maybe even 16 if I'm lucky.
I am asking because it seems every secondary quest that I came across recently require a level 20++ character and I am not sure whether Skellige will have secondary quests below that for me to grind.
EDIT:
it seems I've spoken early. I'm still in Novigrad and now I'm lvl 19 and moving close to reaching 20. Yeah the Dandelion quest was long and I tried doing some other quests that were not recommended because of my level and I was able to complete them, yes they were tough but not impossible.

The main story quest on Skellige is marked as level 16, and it is not particularly difficult combat-wise. You should have no issue doing it, and it'll give you a nice bunch of XP.
There are some other quests on Skellige around level 16-20, so there should be enough to do there. You are more likely to accidentally run into enemies that far outlevel you on Skellige, so you have to be a bit more careful.
Equipment can matter a lot, so if you're having a hard time make sure you have the appropriate witcher set items for your level, or other good gear.
I did switch around Skellige and Velen/Novigrad between levels 15 and 19, there is content on both maps for these levels. I'd recommend to just try out the main quest on Skellige, it should help you level up and you'll find a few more quests for your level on the way. The main quests grant a lot of experience, more than anything else you can do.
