whats too cold ?

minterno

Hi,I was thinking of heading off for a spin but I see the temperature is 1 celcus atm and it looks like there will be frost later on,im just wondering at what temperature do people shut the door and jump on the turbo,im not bothered too much by the cold its only the safety aspect im concerned with,i have 25c tires on my steed,any thoughts?

Air temperature below 3 degrees make ground frost likely.

It's colder than that now and plenty of moisture on roads, I'd don't expect to see much of bike over weekend

Anything 4 or under and I'm out.........note to self add name to wimp list.

Paco Rodriguez

If there is no ice I will be out. Cold helps me cycle faster.

minterno

im ok with the cold to a degree,excuse the pun,just the slippery roads im thinking about

mossym

3 hour turbo tomorrow. Not chancing the roads

Beasty

Used to head out when it was quite a few degrees sub-zero if the roads were dry (usual test was whether ice had formed on the car windscreen). Would certainly not risk that now though

Jawgap

If there's ice I'll pass, regardless of the temperature & windchill. No ice and I'll go.

Today's spin the temp on the Garmin never got above -2 but apart from one stretch of bohereen there was no ice.

crosstownk

Temperature can get up to 5 or 6 but roads that are shaded by trees can still be icy.

I might get a few kms in tomorrow but Sunday morning is not looking good.

Two websites I find good for weather/temperature (probably mentioned before):

http://www.yr.no/place/Ireland/Leinster/Dublin/hour_by_hour.html

https://www.nratraffic.ie/weather/

NRA website tells you road and air temperature and is updated quite frequently

Alek

Once it was -15C and I did not cycle only because I could not find enough suitable layers to wear. But then, I'm from Eastern Europe

nice one,i use the nra website but never came across the other one,cheers

CramCycle

According to my Finnish work colleague, you only stop cycling at -25 as that's when the grease on the bearings in the wheel start to sieze.

The live weather feed from Dublin airport can also be useful, if you live / cycle in the vicinity.......

I just cycled into work. It looked like it was raining when I looked out the window, but it turned into snow while I got dressed. Took it handy, so no KOM's today

triggermortis

Just pulled the trigger on a pair of Northwave winter shoes. Feet were wet and cold this morning after my BBB overshoes bit the dust (zip failed) last week and I used my Decathlon covers (not waterproof in any way). Swiss franc has gone mad against the Euro, so by emptying what was left in my Swiss account into my Irish one, I made enough to cover the cost of the new shoes. Happy out!! (even happier when I have warm feet!)

I can vouch for this. Your breath freezes on your face and eyelashes freeze as well. And the oil on the chain doesn't work like it should. -25 is my limit. But that's on a hybrid with studs. On a roadbike in Ireland I don't think id be out below 4C

Used Spend quite a bit of time in Finland. The differnevery is they cycle in snow with proper tires. Still have grip. I'd head out in sub zero temps no problem, it's the lack of grip that would worry me. Sporadic ice is the real danger, not the cold

Great stuff! We can expect a change to very mild and Springtime weather as soon as they are delivered!

I've used yr.no quite a bit - fairly accurate.

just had a look at the NRA site, never saw this one before - what happened to Limerick?? the west coast looks exceeding odd

smacl

Had the ice tyres on the hybrid for the first time today, though the roads up as far as the featherbeds were fine. Bloody cold though, notably the nose. Will be wearing a face scarf or balaclava next time, as descending was bitter.

The ice tyres are of limited use when there is heavy or slushy snow on the ground. Much better than normal tyres of course, but I nearly came a cropper a few times this week. It was snowing so heavily here, the ploughs couldnt keep up at all. The commute was hard work.

If it's icy I avoid using the road bike, switch to the touring bike instead. I think the coldest I've cycled in is -14 on a mountain bike with studded tyres. Within reason you can go out in any temperature if you're prepared. Don't know what to do about frozen grease at -25 personally but then again that's not really an issue in Ireland.

triggermortis

All my bike is greased with low temperature aviation grease, so thats not a problem. I have had brake and gear cables freeze when the bike is left outside at work. Now if it's really cold, I'll go and bring it in for a defrost for a few hours before I ride home

Bambaata

Today was fine on my route (Dublin - Balbriggan - Julianstown - Ashbourne), we kept tomain roads whuich had been treated and were just careful in shaded areas. We didnt come across any ice at all.

Alek

low temperature aviation grease

Which one exactly? What is its operating temp range?

The wife's just said 'when your balls stick to the crossbar '.

carltonleon

Anything from 3c and roads wet and I am out. If it is dry no problem. I used to go out in colder tempertures but came off the bike on black ice last year on the Balheary Road and it really knocked my confidence in icy conditions. It has made me much more cautious in the ice. I have no problem with the cold or rain but the road conditions are my main concern. I was cycling through flooded roads in November with no issues but ice and i think twice. I took my turbo out into the back garden and onto my deck on Friday and did my session out there. I will probably do the same tomorrow.

Is it easier/safer on a touring bike?

wider tyres, lower pressure, more grip. Also my touring bike is cheap and sturdy so I'm much less precious about it than my road bike in terms of crashing it (I realise my collar bone doesn't get any more cheap or sturdy but I'm young and oblivious so that's not an issue).

Service Temperature High = 180 Deg C

Service Temperature Low = -73 Deg C

Shelf Life = 1800 Days

Looks purrrfect Thanks!

Coldest for me was -8 in 2009 or 2010, roads frozen solid. Studded tyres though. On a road bike I'd be reluctant at lower than 4 degrees here (so could be near freezing up the hills).

CramCycle

-2 this morning, my winter gloves are not as robust as they claim on their description.

I was on my studded tyres this morning for the first time in a while. they sound hilarious. I kept thinking of these guys:

I love the sound that Snow Studs make. It sounds exactly like walking on a fresh frozen snow, -10C and below. Childhood christmas memories

That yr site is savage. Can get temps for towns and the whole lot.

Pinch Flat

Was enough chilly this morning - met.ie saying -6 at Dublin airport when I left the house, but somehow didn't feel as cold. Was well wrapped up with merino baselayer and windstopper soft shell jersey and gloves, so nice and toasty.

Coldest for me was -11 in the snow we had back in 2010 - used a mountain bike I had with the tyres left down a bit. Worked well.

how is it generated though? do they just pick the nearest town with an actual monitored weather station?

That nra have a decent network of sensors that I'd imagine they use

Also met eireann and other bodies must have sensors that data can be tapped into

No. It's weather model output. Weather models use a grid of evenly spaced points and compute the likely weather at those gridpoints. When you ask for a particular town, you either get the nearest gridpoint (up to 10/20km away) or you get an average value calculated from the gridpoints surrounding your requested position.

For current values (rather than forecast), the same process applies. Observations at various stations get assimilated into the model and a 'current values' grid is generated. Then the same value-from-gridpoints method is used to produce your requested values.

Computer generated using the ECMWF model and whatever hiresolution that the Norwegian Met Service use, possibly Hirlam
