Mine are thriving in full sun till about 11:00AM, then shaded. they still look good except for a couple of leaves have that bronzish look to them that Alma mentions. I have been pinching off the flowers when they show up. I'm afraid to cut them back at all right now, because if only the top foliage burns, there is a lot of foliage underneath that can take over after I pinch off the burnt stuff.
My climbing oleander is still doing really well, starting to really grow now that the heat and humidity have kicked in. I hope to see flowers on it this year!!
