32°C in London is not 32°C in Dallas. This atlas translates the current temperature into how it would actually feel in another city — factoring in air conditioning, building design, humidity, acclimatisation, and infrastructure. Click a city to anchor, then hover others to compare.
Methodology: Current temperatures come from Open-Meteo's free forecast API. Each city's climatology (a distribution of typical daily max temperatures for this time of year) is embedded directly in the page so the translation works instantly. The translation has two layers: a percentile match (where today's reading sits in the source city's distribution), then a burden adjustment based on the target city's heat-coping infrastructure — AC penetration, building thermal mass, acclimatisation, infrastructure resilience, and overnight relief.
Honest limits: Burden factor scores are based on documented city characteristics but are necessarily simplifications. Humidity is treated as a typical-for-the-city value rather than today's actual humidity. The climatology is a static late-May snapshot — when this site is properly maintained, it would refresh seasonally.
