Air pressure increases with higher temp. This is why your tire pressure is higher when the tire is warm.
If the outside temp is higher, your tire pressure will be higher to start with. This why the pressure needs to be lowered at higher temp to compensate.
Otherwise it will rise even more when the tire warms up.
