Pardon me while I go convert that to Celcius
... 32˚C... ahh. That's waaaaay too hot for pots that small to be out in the sun all day. As far as how often to water, you need to feel the soil (we can't tell you X times a day or every X days because it varies by the weather). The soil should feel like a wet – but not soggy – sponge. If it's not, they need water. If it is, leave them be. You could use more soil in those pots, too. Fill 'em nearly to the top (take the plant out first, like you're potting on). Deeper soil = more room for roots and more medium to hold water reserves. What do you have there? It's hard to tell from the angle you took the photos. Basil, parsley and... ?
