Hot weather is more forgivable (if you develop that sweat layer between the bus and the games store), but seriously wash your clothes daily and your butt whenever you shower (which may be twice daily depending on the environment). Also bring water everywhere (stores are so weird about letting people use the employee bathroom, even for regulars)

That said, I was recently on a camping trip where it was around 36 degrees celsius and dusty as hell and the showers went down because sewage outflow filled up. Everyone felt super gross and smelly.
