I assume your question is about the commonly held notion that full sun on droplets of water will burn the plant. The answer is no, to that question and to yours. (See “The Myth of Hot-Weather Watering”

Even so, the best plan is to have plants well hydrated before the heat hits. Then, too, it’s worth knowing that plants shut down when temperatures rise into the 90s and, thus, are unable to absorb water. In such cases, it’s more helpful for the plant if you rig temporary shade during the heat and then water later on.
