The Summer Factor: Temperature. Temperature also affects density altitude. When you heat the air, the air molecules have more energy. And, when they have more energy, they spread farther apart. (You probably learned this in high school chemistry class...). When the air is warmer than standard, it's less dense and performance decreases.
Atmospheric pressure is not always the same. If a low pressure system or a high pressure system is passing over your house, that will change the atmospheric pressure. Air pressure also changes as you go up! The air pressure in Earth's atmosphere is pretty strong when you are near sea level. When you go higher up, in an airplane or to the top of a mountain, there is less pressure. Temperature also affects atmospheric pressure. Warmer temperatures will make atmospheric pressure go up.
