Data transparency
The accommodation percentages and city scores are concept data. The source, extraction date, eligible inventory, normalization formula, and rounding method require verification before publication. Temperature values provide context and do not affect the Overall Score; their source and reference period also require verification.
Limitations
This index measures amenities shown in accommodation listings, not citywide heat resilience or heatwave safety. Amenities and availability can change, so travelers should check each property’s current facilities before booking.
