Quick answer: heat amplifies fragrance (bigger projection, faster burn), cold mutes it. So summer calls for light structures — citrus, aquatics, teas — that heat turns luminous rather than suffocating, while winter rewards dense ambers, ouds and gourmands that cold would otherwise silence. Spring belongs to florals and greens, autumn to woods and spices.
The season table
| Season | Families that shine | Keep for later | Why |
|---|---|---|---|
| Spring | Florals, green notes, light musks | Heavy ambers | Mild air carries florals perfectly |
| Summer | Citrus, aquatic, tea, neroli | Gourmands, oud | Heat doubles projection — light juices stay elegant |
| Autumn | Woods, spices, tobacco, chypres | Sharp citrus | Cooling air suits warm mid-weight scents |
| Winter | Amber, vanilla, oud, leather | Aquatics (they vanish) | Cold mutes everything — density survives |
The physics in one paragraph
Perfume is evaporation, and evaporation is temperature. At 30 °C your skin pushes molecules into the air fast: a dense gourmand becomes a ten-metre cloud, while a citrus becomes sparkling and alive. At 5 °C the same gourmand finally breathes at a civilised radius — and the citrus is inaudible within the hour. Neither scent changed; the thermostat did.
Transition seasons: the two-scent trick
April and October mornings are winter, afternoons are summer. Two answers: carry a small format for an afternoon switch, or wear the in-between families — woody-fresh and iris compositions behave respectably from 8 to 25 °C. This is where a small decant rotation beats any single bottle: the right scent for the actual weather, not the calendar.
Should you re-buy per season or rotate?
Rotate. A four-scent wardrobe (one per season) keeps every bottle fresh for years and costs less than re-buying summer flankers. Decant-test each seasonal slot in its real season before committing — a summer scent chosen in a December shop is the classic regret purchase.
FAQ
Can a single fragrance work year-round?
Woody and musky-floral mid-weights can, worn at 2 sprays in summer and 4 in winter. You trade seasonal perfection for consistency — a fair deal for signature-scent purists.
What about air-conditioned summers and heated winters?
Indoor climate flattens the rules: office AC at 21 °C behaves like spring whatever the window shows. Dose for where you'll spend the day.
Are « summer flankers » worth it?
Sometimes — but test against the original: many are simply lighter concentrations you could replicate by dosing down.
