Come to Palm Springs of you really want it hot. LOL
But even worse is in Kuwait (I spent 3 years there), where 120 F (50 C) in summer is common, not normal, mind you, but common.
Santal by Creed helps at those temps, so does Tuscan Soul by Salvatore Farragamo, but if you do not want to throw money away in expensive perfumes, old 4711 or JM Farina do a really good job. Some of Roger & Gallet colognes also can help.
Next time I will try Ginger Ale by Demeter, it must be refreshing, I think.
