Shrike had been living in the mountains prior to arriving in Johto, so he's not accustomed to this kind of heat. As is perhaps evidenced by how he reaches to wipe the sweat from his brow with his sleeve as he talks.

"I-- I don't like it when it's short."

His face isn't all he's keeping hidden from others' sight.
