Did you decide to move to Panama?
'El verano' or summer in Panama occurs during winter months because that is the dry season here. The school year in Panama also follows this schedule and kids have their summer break just after the New Year. So to sum it up, the weather is much nicer - hence must be summer.
That's my take on it.
