Vetiver extraordinaire is perfect for the summer, it's superfresh. In diptyque, Tam Dao has its estimators, but it's woody, so perhaps not perfect for the summer - rather, I think things like Philosykos (fig leaves and fruit) or Ombre dans l'eau (green. ideally in edp) might fit better.
Histoires de Parfums tends to do heavier stuff (like 1740), but I think Rosam could work, if you like modern frags. It's a very clean, metallic rose with some metallic notes. My favorite Kurkdjian is also a heavy musky one (absolue pour le soir), aqua universalis is fresh and clean, but perhaps you can wait for the winter. Rather, I think I'd look into Heeley's, like Sel Marin (salty, beachy).
Finally, as usual with the first approach in niche, I think it's best to be patient and smell a lot first. Try to smell stuff when you go to a big city. There are so many things around that it pays to smell around first. You may like the first thing you smell, but then discovered that there are many more things you like more.
