I have never in my life seen such temperatures! Very humid here too. Yesterday, we had torrential afternoon rain. Places flooded that are not normally flooded. The North Island has experienced 11,323 lightning strikes yesterday. Late last year, driving home I experienced a lightning strike so close. It was ear-piercingly loud, bright and I could feel the static in the air. Too close for comfort.
I would worry about dry strikes too given the high temperatures drying everything out.
