Perfumes can perform differently in hot or cold climates for a few reasons. First, heat and humidity can affect the evaporation rate of a perfume's scent, causing it to fade more quickly in hot and humid conditions. This can make the scent of a perfume less noticeable and less long-lasting in hot and humid environments. Second, extreme temperatures can also affect the chemical composition of a perfume, causing its scent to change and potentially become less pleasant. Finally, people's sense of smell can be affected by changes in temperature, which can impact how a perfume smells to an individual in different climates.
