Well I'm only brand-spankin-new to Bpal and the forums, but I've come across a few so far that feel rather summery to me - which is good since it is summer in my part of the world!  Although, I prefer the warm, spicy, snuggly scents - so I'm looking forward to winter!   
  
If you can do the lemon thing, all these guys smell very fresh and summery to me (although lemon just doesn't work on my body): 
Enbalming Fluid 
Phantasm 
Zephyr 
  
Others I find bright and cheery: 
The Unicorn 
Cathode 
  
And my favourite so far as far as summery smells go - Ya-Te-Vo  it's really green smelling to me - but not tree/moss-like, more freshly clipped hedges and things like that.
