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.
Because of the change in atmospheric pressure, barometric pressure lowers which then turns air to press outward putting pressure on the sinuses. This could trigger migraines and could mean that someone might even feel severe pain caused by changes in altitude or in temperature.
