Hot Day = Gas Expansion
Normal bottle pressure is about 700psi, but when the bottle is in a hot environment in full sun the pressure can increase to what is seen here to be 1300psi. Still in the safe zone, but just shows Gay-Lussac’s Gas Law in action. (This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up.)
