Weather and perfume
Does heat make perfume stronger
Warmth can change evaporation and the impression of a fragrance, but it does not guarantee stronger projection throughout the wear. A prominent opening and long duration are different outcomes.
A HUME Fragrance buying guide

Understand the limited inference
Temperature affects evaporation in general; a finished perfume contains many materials. That principle cannot supply exact hours or distance for your bottle.
Observe opening and later scent
Record whether the start feels more noticeable and what remains later. Do not treat those as one strength score.
Never heat the bottle to test it
Use ordinary wearing conditions, following directions. Deliberately warming perfume is not a useful way to improve its performance.
Try this before you buy
Compare the initial impression and later presence separately during normal warm-weather wear.
