Sure, we have constant watering here, too, with very low humidity and high temps. We hit 119F a couple years ago. Many things have to be moved out of the sun to protect them in mid-summer. Lotus will get a bit crispy above 110F, but will be fine as long as they have sufficient water. When possible I want the leaves sunlit and the water and pots fully shaded in the summer.
I've heard from people in cooler parts of the country who've had issues, though, in the beginning of the year when trying to start before the water's warmed up, or with a lack of growth or blooms once it cools down again.
