CHILLY
A light jacket handles the day's swing.
12°C sits in the middle of the chilly range (10–16°C) — the most typical case for this band.
In an average year, 12°C turns up in March, April, October and November. Those months share this temperature, so their outfits carry over directly.
Compared with 11°C you can drop a layer, and from 13°C upward you can leave the outer layer at home more often.
What 12°C feels like in different conditions
12°C is chilly — and often the trickiest temperature to dress for, because the day swings widely between a cool morning and a mild afternoon. The trick is one light layer that handles both.
A trench, cardigan or denim jacket you can easily take off and carry is the answer. Put a sweatshirt or thin knit underneath, and just shed the outer when it warms up.
This is where the daily swing bites hardest. An easy-on, easy-off cardigan or light jacket makes the day work.
What to reach for
Dressing for the cold morning means carrying it all afternoon — a layer that folds into your bag wins.
One adjustable outer layer does the job. A light jacket over a sweatshirt absorbs the whole morning-to-afternoon range.
What to reach for
Dressing off the daytime high alone leaves you cold at 8am. Outer for the morning, base for midday.
What to avoid — A heavy coat or puffer becomes dead weight by afternoon; a single tee is too cold at dawn.
In the morning and evening, yes. Even if you take it off midday, carry one light layer — the daily swing is the whole story of this band.
Split it: outerwear for the morning temperature, base layer for the afternoon. See the transitional-layering guide for the full method.
On days with a high afternoon peak, a tee plus a light jacket is perfect — just don't leave the jacket at home.
A light jacket or trench over a long sleeve. Mornings at 12 degrees Celsius feel colder than the number suggests, so pick something you are happy to keep on all day.
