Cilantro will bolt (go to seed) based on temperature and longer day length. Shading the plant in high heat will certainly help the plant cope in general, and might possibly delay bolting for a little bit; you can also keep cutting the flower stalk as it forms to delay it. The plants do not like humidity, and some might become stressed enough to bolt; humidity can also encourage certain diseases. In Florida, cilantro is usually grown in fall and winter, to avoid the higher temperatures. If a plant bolts, though, you can eventually harvest the seeds as coriander.
