Plain answers to the question you actually asked this morning, which is not "what is the dew point" but "what do I put on."
-
What to wear in 20 degree weather
A long sleeve, a sweater and a parka, with jeans and boots. But 20°F is the last degree for jeans, and a 3 mph breeze makes it feel like 16°F, which is enough to put you in a thermal layer, insulated pants and winter boots.
-
What to wear in 70 degree weather
A t-shirt, jeans and sneakers. Not a hoodie: that stops at 62°F, eight degrees lower, and shorts don't start until 80°F. The thing worth planning for at 70 is the evening, so carry the hoodie instead of wearing it.
-
What to wear in 40 degree weather
A long sleeve, a hoodie and a puffer vest, with jeans and boots, and no coat. But 40°F is the last degree of vest weather, and a 3 mph breeze makes it feel like 38°F, which is enough to put you in a puffer and a beanie.
-
What to wear in 30 degree weather
A long sleeve, a fleece and a puffer, with jeans, boots, a beanie and gloves. But 30°F is the last degree before a parka, and a 3 mph breeze, about the least wind the formula counts, is enough to push it over.
-
What to wear in 50 degree weather
A long sleeve under a fleece, jeans and sneakers, and no jacket yet. But 50°F sits two degrees from two band edges, and it's the exact temperature where wind chill switches on, so a 10 mph breeze is enough to change what you wear on top.
-
Is it jeans weather today?
Jeans hold from a feels-like 20 to 74°F, a 55 degree window and the widest of anything you own. Which means the answer is nearly always yes, and the decision worth thinking about is the top half, because that changes seven times across the same stretch.
-
Do I need a hoodie today?
A hoodie fits on its own between a feels-like 52 and 62°F, and the answer flips on a single degree at the top. Below 52°F the hoodie keeps working but the t-shirt under it has to go, which is the part every fifteen-degree range on the internet skips.
-
Do I need a coat today?
A coat starts at a feels-like 39°F, roughly ten degrees colder than the usual advice. The difference between a coat and a jacket turns out to be two warmth points, which is why the answer flips on a single degree, and why the 40s want a vest instead.
-
What to wear in 60 degree weather
A t-shirt under a hoodie with jeans, and that covers most of the day. But 60°F sits two degrees below a band edge, which is why one profile question is enough to take the hoodie away entirely. Plus the 20 mph wind line and why September's 60°F is colder than March's.
-
What temperature is shorts weather?
Shorts weather starts at a feels-like 80°F, about twelve degrees later than most people put it. The reason is that trousers are the one decision you can't revisit at 3pm, plus what sun, humidity and the evening drop do to the line.
-
Cold morning, warm afternoon: how to dress for a 25 degree swing
A 25°F swing needs two removable layers, not one. Your base layer, trousers and shoes are all locked in the moment you leave, so all three get picked for the afternoon. Plus why the same swing costs four times more at the cold end.
-
Why am I always cold when everyone else is fine?
Your comfortable temperature is a real number, and it can sit 10°F (6°C) away from the person at the next desk. The physical reasons it shifts, the part that's only acclimatization, and how to find your own.
-
Feels like vs actual temperature: which one should you dress for?
Dress for the feels-like number. But wind chill quits at 50°F and the heat index doesn't start until 80°F, which leaves a thirty-degree gap where most apps quietly show you the thermometer instead. Here's what the number measures, and where it misleads you.
-
Do I need a jacket today?
Jacket weather starts at 62°F and stops being optional at 52°F, but the number that actually matters is where a light jacket quits. Here's the full range, the layer arithmetic behind it, and the temperature where the puffer takes over.
-
Is it hoodie and jeans weather today?
The hoodie and jeans window is narrower than most people think, and it's measured in feels-like degrees. Here's the full range, when the jeans are the problem instead of the hoodie, and the two numbers to check before you get dressed.
