Most people notice that a fragrance they loved in summer behaves differently in winter, without being able to say why. The explanation is simple and chemical: scent opens with heat.
What temperature does
A fragrance is perceived as it evaporates from the skin. In heat that process speeds up — the scent opens faster, projects more strongly and finishes sooner. In cold the opposite happens: it opens slowly, projects less, and lasts considerably longer.
The practical consequence: summer favours light citrus or aquatic compositions, because heavy bases become overwhelming in heat. Winter is the reverse — a light fragrance is barely perceptible in cold, so denser bases of amber, vanilla and spice do the work.
One important caveat: this does not mean there is a separate product category called "summer" or "winter" perfume. Choosing a lighter or heavier member of the same family is enough. Our longevity guide covers this in more detail.
Colour follows the same logic
Interestingly, colour choice follows the same dynamic. In summer light and saturated colours read well in strong daylight; in winter the same colour can look washed out and out of place.
On everyday objects this is the easiest part to adjust. Changing something small, like a phone case, with the season costs a fraction of changing a wardrobe. For summer, tropical prints and lighter tones feel natural; for colder months single-colour, darker options do.
What to do in the transitional months
Autumn and spring are the hardest, because the temperature swings through the day. The solution that works is simply using less: the same fragrance, a smaller amount, applied close to the skin.
The second solution is neutral bases. Musk and light woods behave similarly in cool and warm air, which makes them the most reliable choice in transitional months. Our unisex section is full of this type.
A warning about storage
The most common seasonal mistake is keeping a fragrance on a windowsill or in a bathroom. Temperature swings and light degrade a perfume faster than anything about the scent itself — a few months is enough.
The right place is cool, dark and dry: an ordinary cupboard shelf is entirely sufficient. Keeping the box is the cheapest protection available.
