I actually searched for that exact question before I turned on the sprinkler. Search for "does watering plants in sunlight burn them" and there's tons of results claiming it's not true. Sources ranged from The Guardian to StackExchange. I was desperate and those search results were good enough for me at the time, so never bothered to look for any kind of studies around the matter. If you can find evidence of watering in sunlight burning plants, I'd like to read it. EDIT: Here's an interesting experiment on it: https://nph.onlinelibrary.wiley.com/doi/full/10.1111/j.1469-8137.2009.03150.x https://nph.onlinelibrary.wiley.com/doi/full/10.1111/j.1469-... > At the start of this paper, we quoted the oft-stated advice that plants must not be watered in the midday sunshine in order to avoid tissue damage as a result of intense sunlight focused by water drops on leaves (Table S1). We have shown that this widely held belief is only correct for hairy leaves. Based on the computed light-collecting efficiency of water drops (Figs 4–7), we have also determined that the risk of sunburn of smooth, hairless leaves is theoretically the highest at a solar elevation of θ ≈ 23°, corresponding to early morning or late afternoon. In practice, however, the light intensity from such an oblique position of the sun is too weak to be a factor, as was confirmed by Expt 2.
