I sit in the west stand for Hull FC games just to the left of half way line and it feels just as cold there at times even thought its spring. Always in the shade at that side.I moved to the West Upper last season and I’ve yet to experience a “cold” game up there. In the East, it used to be awful some games how cold it’d get. Don’t seem to be affected by the wind up there and other than the Chelsea game with that snow, we’ve avoided wet weather too as the rain usually gets blown onto the North and East stands.
Its a weird stadium, sat feeling cold watching the East Stand basking in the sunshine. Then for city games im in E10 and even in the sunshine seem to still need a coat. Maybe its just me!!
