It is too cold to go out. How should I reply?

Yes, it's too cold recently. It's too windy outside. It's too difficult to go out. I don't want to go out. If it is too cold to go out, you can consider it in another way. You said, let's go out for a walk, hang out together, go somewhere to play and watch movies. You can go out as long as you want to ask him out.
