Oh for sure you could wear it in summer! I've never had a problem wearing spicy scents in summer. The really sweet ones are harder for me to deal with. When deciding what will be wear well in different temperatures, I go by the scent's dryness instead of note technicalities. If something is sweet and "moist", I feel enveloped in a cloud of steamy, syrupy, sillage. So a scent can be rich, spicy, and woody, but if it feels arid on me, bring on the summer heat. Fahrenheit is a good example of this.
Anyhow, I believe that L'Air is about as dry as it gets in perfumery. Completely fitting for summer. If all else fails, just wear it one day and see how it suits you in the heat.
