This guy , to me, made a nice full range temp guide(post #4 )
https://www.bikeforums.net/winter-cyc...tml#post850391

should solve all temp questions

Use this as a guide. As you ride, record what you wear and what the wind and temp was like. You will end up making your own guide.

This listing was a good place for me to start.

Not everyone has lived in the same place all their life.

Ever thought of a pair of long Johns? They make them for hunters, fisherman, outside workmen. They are light and comfortable. Then a tougue and/or face balaclava and gloves and a little spiced rum in your 2nd thermos..

I feel like maybe spreadsheets breaking down every possibility into five degree buckets is maybe a little overkill. Once you've done some riding, you should be able to step outside most of the time and see how cold it is, then have a pretty good idea what to wear (without having to ask your phone). Just dress for the second mile.

Like everyone said: layers. At minimum, get some basic leg and arm warmers with a packable vest. Add a softshell jacket for colder temps as you head into winter.

The thing with layering: it changes from fall to spring. Meaning as you acclimate, 60 at the end of summer feels way colder than 60 at the beginning of spring.

One winter, I was riding with ice on the road wearing non-insulated shorts, leg warmers, sleeveless base-layer, regular short-sleeve jersey and a softshell jacket. But going into fall, I might wear that same setup at 50 degrees coming down from day after day of high-90's temps.

For me "winter wear" means arm warmers maybe 3-4 times during the winter... south Florida here. But here's a good guide

Ha! I do this too. My riding buddies think I'm a little nuts for it but I guarantee you I dress a lot faster than they.

Canadian asks about cold weather riding. Americans respond with temps in Fahrenheit.

Fail!

Fly2High

Since the US rules EVERYTHING, they should be use to converting the numbers.

rousseau

I know you're sort of joking, but you're inadvertently making the fail even stronger. Because, think about it: why would anyone here be "used to converting the numbers"? What would be the point? Everything here is in Celsius. We (well, unless you're 70 years old) don't think in Fahrenheit temps. When would we ever have the need to convert them into Celsius?

His fall temperatures are probably about as cold as it gets in January here. FWIW, yesterday it got down to 11C and I was comfortable in armwarmers and kneewarmers. Bare hands. I started with a windvest but took it off. Again, YMMV.

RPK79

I didn't know they used Celsius in California.

When dealing with Americans. And since Canadians deal with Americans more often than any other country, they should be used to it.

They don't. But they should. Just like roundabouts and universal healthcare, the metric system makes perfect sense and the rest of the world knows it, but Americans refuse to accept. (I'm bi-systemic from living abroad a few years ago.)

RPK79

I'm sure with modern advances to medicine they will be able to treat this eventually. I'm sorry to hear about your affliction.

What I would choose for fall wear in coastal Massachusetts may or may not work for you in Ottawa. If you start out here in the early morning, and do a ride of any length, the temperature may rise by 15-20 degrees, over the course of those hours. That's why arm warmers and leg warmers are often a better choice than tights, and heavier base layers. It warms up, take them off, fold them up, stick them in a jersey pocket.

Fly2High

He means about 8-10 deg. C

And yes, I was completely joking. I was just back from a business trip to France and have relatives in Italy so I have been exposed to converting temps when they speak. It takes effort to think that 20 deg. C is 68 and 30 deg. C is about 86 in Fahrenheit. Feel odd to think a mere 10 degree difference spans indoor normal temps and the hotter days of summer but it is what it is. I recall the 70's and 80's and we tried to integrate to the metric system but it didn't take. Ironically, it did take in all aspects of scientific writing and research. Why we cannot convert, I do not know. There is a simplicity of having available decimal values instead of fractions of 1/8, 1/16, etc. and the odd units of feet, yards and miles. I would bet the average American needs a calculator to figure out how many yards in a mile but every one on the metric system can tell you how many decimeters, centimeters, and meters are in a kilometer.

It is just different

as for us reporting F instead of C, many forget that these forums are global, even if the site is in America so forgive us for our small view of the world.

rousseau

I deal with Americans in my business every day. Correction: I deal with Americans who aren't idiots every day. Everything temperature-related is done in Celsius.

Because they aren't idiots.

mprelaw

(F-32) x 5/9 = C. Some of us can do it in our heads.

For the rest of you, the calculator app on your phones.

RPK79

I'm curious, what business are you in that you discuss temperatures at all?

ColaJacket

Well, if you're dealing with Americans (Engineers/Scientists) on science based projects, that's understandable.

I suspect you're not dealing with average Americans regarding the weather.

A lot of scientists and engineers that use Celsius (or Kelvin) in their job, still use Farenheit when talking about the weather.

rousseau

That's top secret. I can share that it doesn't involve discussions, just scientific, medical and engineering documents.

mprelaw

Metric conversions aren't all that hard. I adhere to the "when in Rome" philosophy. In Europe, I do Celsius, dd/mm/yyyy notation for dates, 24 hour time, and kilometers. Unless you're a scientist, the conversion doesn't have to be exact. 4 litres is a little more than a gallon, when buying gas. A kilometer = .6 miles , and double kilograms and add 20% for pounds.

I learned all of this back in the early 70s, in high school, when we were told that by 1980, the US would join the rest of the world and adopt the metric system.
