Looks a little stressed from low humidity, sunburn, and the recent heat waves, but other than than that, your plant is totally fine. You're in a hotter area than I am, so I'd blame those recent heat waves for most of the stress. When it gets really hot and you have low humidity, the leaves will fold up, but once night hits, they tend to get turgid again and look totally normal.
How do you combat this? Grow a bunch of bananas next to each other. They create a micro-climate and increase the humidity. I have a banana plant growing by itself, and it's almost always sad during the day, notice the droopy leaves. This is from being stressed out by low humidity, high temperatures (mid 90's this week), and high light intensity:
A few hundred feet away, these plants create a highly humid environment, and under the exact same weather, they don't ever wilt (anymore) now that they're bigger. When they were smaller, the leaves did fold up, but as the plants grew a giant canopy, that all changed. The overall micro- environment has become more humid since they're crowded together:
