They are usually fine, but depending on how hot they got, they may be stressed. I only ever had a couple of dead yeast packs, and those were shipped from Texas to Florida during the middle of summer. Those cold packs usually melt within a couple of hours of packaging.
I would try and buy your yeast locally during the summer if you can. It may be a touch more expensive, but the yeast companies send them in insulated boxes via second-day air to the homebrew shops. When I take delivery of them at the shop, they are rarely warmer than about 75 degrees even in the middle of summer.
