Drink more water than you usually due to compensate for the heat. If you're gonna be outside for long periods just be careful and gauge yourself on thirst, just grab another cup of H20. Maybe even grab a little sun tan lotion if you know you"ll be in the sun for more than 20 minutes.
And since this is LA don't forget about doggos and cats they need extra water too and a place to stay in the shade.
