Low hot water temp. from gas water heater in hot weather.
How much insulation is on that tank? Is it in place that is air conditioned during hot season, heated during cold season? How long is run to nearest faucet, pipes in AC'd heated area? How long is "a while"? I don't think AC would have that much effect on heater, it would just come on more often, but...
Sure you don't have your thermometer upside down and are confusing hot weather with cold?
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
