How the score works
One number out of 100, blended from the four factors below: comfort, crowds, prices and weather. Higher means go now. Lower means queues, rain and paying more for the privilege.
Factor breakdown
Crowds
How many other people had the same clever idea. Built from researched monthly visitor patterns, then pushed harder for public holidays, school breaks and big events.
Weather
The weather that cancels plans rather than just dampens them. Built from monthly climate baselines plus researched storm, typhoon, smoke and snow periods.
Prices
How much the dates themselves cost you. Built from researched monthly demand, with the same holiday and event surges that drive the crowds, because airlines can read a calendar too.
Comfort
Whether you will enjoy being outside or merely endure it. Built from average highs and lows, humidity and rain risk.
