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.
Air pressure changes with the weather. In fact, it's one of the most important factors that determines what the weather is like. (Related: How high and low pressure affect the weather). You can do some basic weather forecasting by using the wind and barometric pressure.(Related: Using pressure, wind for forecasts).ir pressure changes with the weather.
