Hmmmm...As a Southerner, heat and humidity is no big deal. After April arrives, they are a way of life. When it's pipe time, I stride purposefully into my tobacco vault and lovingly admire my inventory, carefully straightening the more or less orderly arrangement. After musing for a bit over the pleasures of future pipes, I inspect my working rotation. Something always jumps out at me as the tobacco of the moment and I go from there. If it strikes my fancy, I will happily smoke any type of blend any time of year. Piping is a pleasure and, as with most pleasures, shouldn't be over thought. Just my view from the west pasture. :D
Cheers,
Chili
