In all honesty, the operating temps inside your engine far exceed 110 degrees F, even during the winter, and your car's cooling system is designed to maintain a particular range of temperatures, so whether it's 80 degrees or 110 degrees won't really make much difference in terms of what temps the oil experiences.
Having said that, I live in Phoenix, and we regularly see temps well over 110F during the summer, and generally speaking, I like to up my oil weight for my oil change right before summer.. not always, but frequently.. Does it genuinely make a difference? Probably not, but for some reason, I feel better doing so. Doesn't seem to impact anything besides perhaps a ~5% drop in fuel economy, which could just as easily be due to A/C usage.
