For a growing share of travellers, high summer is no longer the default. Heat, crowds and peak pricing are pushing demand into the shoulder seasons, and the pattern is now consistent enough that operators are repricing around it.
Destinations that once emptied in the off-months are extending their calendars, and some are actively steering visitors away from the crush of the peak.
The upshot is a flatter, longer season, and a travel year that looks less like a single spike and more like a plateau.
