What kit do I wear when the weather is on the turn??

I've got a pair of (non-cycling) Columbus Sportswear windproof gloves that are perfect for this sort of weather. They have a reflective foil lining, palm and finger grippers, and you can use smartphones with them. And on sale at the moment:

Armwarmers, kneewarmers, gilet, light full finger gloves, oversocks.

Pretty much essential items during the spring & autumn transitions.

Pretty much what everyone else has said.  A pocket-sized gilet is the most useful piece of clothing, plus  LS baselayer (I can pull the sleeves up if need be), ordinary jersey, arm warmers, and either bib shorts and knee warmers, or calf length bibs from Decathlon (the former if it's going to be warm on the way home).  Arm warmers and gilet usually get removed at about the 20 minute mark (after a big descent, which is always a delight last thing on the way home)

I've been looking at too many "Close Pass of the Day" videos and have a whole new wardrobe. I'll just add some extra padding to keep out the winter chill.

Still in shorts at present and short sleeves though this is with arm warmers some days and have added a mesh base layer. Will make the switch to full sleeves in November along with knee warmers or 3/4 bibs, this also means swapping the drawers around. My kit is divided into winter and summer drawers.

My wardrobe above was based on the crazy changes in temperature of the past few days down on the South Coast. Waking up to temperatures of 8 degrees for the morning commute and nearly 20 for the ride home. 

If it is wet and cold then my choice of clothing would definately change and so would my choice of footwear. Overshoes instead of oversocks as ClubSmed points out for example.

Met Office.gov.uk local forecast the night before and, if unsure, a morning check of the latest Met Office readings from the local weather station (about 2 miles from my workplace). I prefer to put up with feeling a bit brrr! for the first mile or so because I find it much more tolerable than being too hot by half way.

11-15°C normal jersey with arm warmers and either knee warmers or 3/4 tights;

< 11°C lightweight windproof jacket, cycling cap (easily removed once warm);

Below about 8°C long sleeve merino baselayer under the jacket and full length tights.

For your start I'd perhaps a gilet might be worth a try. A 5p carrier bag under the jersey or jacket is an emergency/cheapskate way of keeping cold air off your chest.

There are so many variables it's hard to say at x temperature on x type of ride/ride intensity that you will definitely wear x clothing each time. Even relatively small differences in temperature/other weather, effort, how you are feeling can change what you feel you need to wear. I'm far less susceptible on my legs than upper body, I think that's fairly normal however.

But that said,10C-16C it'll be shorts (this could be my sports or walking shorts which I use a fair amount for commute/utility) and anything from a std short sleeved jersey to a long sleeve thin jersey if it's closer to 10C, it could also be a thin short sleeve jersey with a spring/autumn jersey if there's a bit of wind and/or closer to the lower temps. I might wear my 3/4 bibs or longs just because they're to hand and a biting wind or knowing I'm coming back late when it'll be much lower temps and setting off 'cold' with a short journey, will draw me more toward them, also my longs tend to be a bit more modest in terms of sitting with friends.

I did buy some arm warmers last year for the first time but I've worn them once, it just seems hassle to put them on when you've a thin long sleeve top you can put on.

I think we all have a ridiculously large wardrobe with many garments for different occasions/temperatures/weather

I’d agree with start cold and warm up.  It can take 3 or 4 miles before my hands get comfortable.

Another one for Castelli, I’ve pretty much fine tuned my setup now, although I do tend to run hot. I just open the zip to cool down if I’m in a windproof.

• cold ish and damp Gabba, endura baabaa ss and arm warmers, omloop thermal bibs (high single digits) 
• dry, swap for an alpha wind jersey (today) or a LS stolen goat (not windproof)
• colder and wet or dry Perfetto and ss baabaa, sorpasso 3/4 (low single digits) Planet X 365 gloves
• cold and wet or dry Perfetto, full length sorpasso and LS baabaa (very low single digits to zero) same gloves.  On a long ride (200k) in these conditions I used a pave waterproof and a LS stolen goat as I knew a gabba or alpha would wet out.
• very cold, full length sorpasso and alpha jacket with ss baabaa (down to -7 so far) warmer gloves.

Always Shimano goretex mtb shoes with merino socks and endura overshoes.

There’s quite a lot of overlap in the comfortable temperatures for these, so it generally works well enough.

3/4 are brilliant for this weather. 

Tights for the first time since April this morning... plus a 20yr old Assos windblock jacket that won[t die.  They're all set out for tomorrow morning's ride too.  With overshoes.  It's cold at 5am...

Shorts and a Castelli Perfetto from now until winter starts to bite, then shorts, leg warmers and an Alpha ROS.

The Castelli jackets are good. Really good.

Never tried the Castelli stuff (Gabba/Perfetto) but I have a Gore Windstopper jersey and love it. It’s short sleeve and in that and with a pair of arm warmers (mine are sportful no rain, which like the jersey are good in light rain as well and feel windproof) I’ve ridden in temperatures between 4 degrees to late teens.

Choice of shorts/tights, gloves and potentially base layers to fine tune to taste and stick a packable softshell/gilet in the back pocket to cover a LOT of grounds! Works for me, anyway

When its cold (but not REALLY cold) I commute in wearing bib shorts and a long sleeve jersey with thermal leg warmers and a merino baselayer (and merino socks with thick gloves).

When it's chilly, I wear the above except I don't use the leg warmers and use a lyrca baselayer instead of the merino one (and some thin full finger gloves).

When its absolutely freezing, I wear thermal tights, merino baselayer and a thermal jacket.

Obviously, when the weather is like it is, it can be frustrating because I have to take extra (thinner) baselayers/gloves to wear on the commute home. And it's further frustrating as what I wear will change day to day.

Once you have 4 variations of kit for; supercold, cold, chilly and fair weather conditions - it's fairly easy to wear the rights stuff - guessing the weather and making sure the right combination of clothes is washed for the next couple days is the real challenge!

Just bib shorts and shoes, nothing else.  Don't go outside on UK roads from September till April.  Conservatory is my road and this

When I got back into road cycling a few years ago I was a bit dismissive of winter specific clothes (just manufacturers trying to get me to spend more money) and just tried to layer on top of my summer gear (tights, gilet, rain jacket), but did feel a bit hot and overdressed.  I have renaged and now have some winter gear (long bib shorts, base layer, winter long sleeved jersey) and I have to admit they work well in the colder months; enough to keep the cold out and not get too sweaty.  Hands and feet are things I don't compromise on, so decent gloves and overshoes.  I try to avoid the rain jacket unless it's actually raining as, despite claims of fantastic breathability my manufactuers, they make you 'cook'.  I do tend to push it more commuting, so heat management can be hard to guage.  It's amazing what you can stuff into pockets when you try!

Rule #5

Cold morning:
1. short sleeve winter base layer
2. short sleeve jersey
3. arm warmers
4. gilet
5. long finger gloves
6. bib shorts
7. knee warmers
8.over SOCKS

If it gets too hot on the ride (the uphill part of the commute), stuff gilet under the ss jersey.

Home commute (warmer):
1. Ditch the knee warmers, gloves, arm warmers,over socks and gilet. Stuff in jersey pockets or rucksack.

Always start too cold and warm up. Never too warm and get cold through sweating. It is more difficult to regulate body temperature once you have overheated.

I tend to go woolie (defeet merino) socks, bib shorts (until it goes below 5c then tights come out) then either baselayer + Jersey + thin jacket (cold) or jersey + thin jacket (less cold) or baselayer + Jersey (nippy).

On the way home when it is often warmer I drop a layer and stuff it in my bag. Basically layering is key.

For me I concentrate on the headband, gloves and overshoes to keep the cold out. These are also small items that you can keep in your bag so if you leave without them on you can pop them on when you realise you have made a terrible mistake with the weather.

I wear one of these: https://www.decathlon.co.uk/road-r-500-ultralight-windproof-cycling-jack...

Keeps the wind off to start with and packs up small enough to fit in a jersey pocket when I warm up.

It's good down to about 10 degrees with a short sleeve jersey or 0 with a long sleeve... Anything below 5 though and I wear this: https://www.decathlon.co.uk/900-hi-vis-warm-cycling-jacket-yellow-id_836...

If you don't want to stop to pack up a layer, try arm warmers?
