Where you live ... is it too hot to cycle?

What's your cut off point when it comes to heat?

Personally, I miss heat. When I lived in Manitoba, we'd get a lot of nice mid-30s days ... some with "feels like" temps in the 40s if the day was particularly humid.

We don't get those kind of temps down here in Tasmania.

And it's winter right now, so we're lucky to get up into the low teens.


Enjoy the heat!

I haven't found a limit yet.

Although I did have a minor "heat event" last year on a Cat 1 climb at 96 degrees. No breeze at all and I overheated as well as messing up on my electrolytes that ride. Actual made it harder for the body to handle the heat for several weeks afterwards. This summer we are unusually hot here so lots of rides in the high 90s. Even did a hard one the other day at a 97 avg despite being sick. I was good the first hour but the last 6 miles were not much fun, LOL!

The rule of thumb here in Florida is get out before 7AM in the summer months. I got out "late" last week (7:30AM) and the temperature was already 78F.

30° C (86° F) is kind of a cutoff to me. As it gets into that neighborhood, I'll be much more careful, riding more gently and hydrating more obsessively. When it's going to be that warm, I try to go out early, before it gets that warm (I don't always succeed, especially if it's a very long ride).

I don't have a cut off point , but I do take it easier on very hot humid days....This summer felt exceptionally hot and humid with temps regularly going into 80-90 F and humidex of 113 F, most summers here are not like that and this year has been different Even with .lower temps it still feels hot because of humidity I don't mind dry heat but high humidity just kills me. I much prefer colder weather.

Nope, you 2 have been here.. I saw the pictures ..

Marine Coastal climate .. high 65F , low 50 F.. overcast till noon, now..

Here in W. central Georgia, we've been solidly in the 90's, with heat indexes pushing 100, and I've been doing 3.5 hour road rides, nearly every day, with two climbs over our resident "mountain". I try to be on the road by 9 a.m. but today it was after 10:00 ( but i only did 2 hours, cuz my quads were feeling puny today, and I have stuff to do later.)
I used to race and train in Cozumel,Mexico, a climate even more oppressive than the steamy south, and I only recall a single day where I was thinking, "Good lord, this is just too hot !!!!" (it was a crit-like race up and down the length of the airport road, in the afternoon in August IIRC).
Mostly, I've always felt comfortable riding in very hot weather. It's the cold that zaps my will to be out there !!!

0 Fahrenheit to 100 Fahrenheit are my rough limits.

Too hot here for me. Generally I ride up to about 85 during the day. In the summer the wife and I usually do our riding at night, but right now it's still over 100 at midnight. In previous years this wasn't an issue, but I am riding a lot more these days and I don't like missing out on training, so it's time to buy a trainer.

Yall are pansies. 110 or so by the end of the ride is a max. I try not to start a ride hotter than 95 or so.

I try to be done with my ride before the temps get over 100. Yesterday was bad since the low was 86 and I ride late mornings usually, and before that we were getting record highs. I just take it easy and keep hydrated when it is real hot. Even the pool feels like a warm bath right now.

Heat isn't the problem it is heat and humidity/dewpoint.

On heat-warning days, you can still get miles in...so long as you are prepared to be on the bike before civil-dawn, and get miles in before daytime heating makes it worse. dawn is better than dusk, as it can still be dangerously hot/humid far past astronomical-sunset


Most of May/June it was about 100F ambient and 75F+ dewpoint. Still rode---but I was on my bike, riding by, 0530.

I go by dewpoint (and the related heat index) more so than temperature - something I learned after moving from the arid American West to coastal Alabama and then the Upper Mississippi River Valley. 95F, even 100 was perfectly fine with a low dewpoint, but kills me when it's humid!

Generally:
- Dewpoints 70-75F: I will prehydrate, choose an easier route, and do any climbs very slowly.
- Dewpoints 75-80: Prehydration plus no climbing.
- Dewpoint over 80: Norecreational riding - transportation riding will, if possible, be delayed until it cools down.

Fortunately, western Wisconsin rarely has dewpoints above the mid 70s F. I did a few commutes in Alabama in that last category, and it was awful - much worse than my 112F commute during a Santa Ana event in California.

I just don't like the discomfort with the humidity accompanying hot days here. Lucky me, I'm a night-owl and usually go to bed about 2:30am, so sometime after 10:00pm I'll put on my highway safety vest and roll out. Humidity doesn't drop that much, but temps do, quite a bit, and out where I live I pretty much have the roads all to myself, especially after midnight.

I went out for a ride last night, just half an hour. Air temps maybe middle 60s; I'm in shorts and a very well-ventilated shirt. Got home and brought my bike in the house--it's maybe in the upper 70s inside--and it felt like an oven; I had to go back outside and walk around a while to cool off.

I've also got a membership at a 24-hour fitness center for when it rains. Nice going there late at night, too; I don't have to wait to find equipment to use.

It's been mostly pleasant here, I think my GPS maxed out at ~89f, but it was closer to 75 for most of the ride.

It's been in the middle 80's here for a few weeks. I still bike commute, but I sure do get more damp doing it.

Nothing at all like the high 90's low 100's where I used to live. That wasn't pleasant from about 9:30am until about 6:30pm.

90f is fine for me, if the humidity is low. 85f with high humidity I tend to keep rides under 30 miles unless I have something planned.

I'm very fortunate to live not too far from the coast where it's rarely very hot. If it's going to get above 90 or so where I live, I leave early and go to the coast. I do have to ride through some heat coming home but only about an hour or so.

I've ridden up to mid 90's but don't like to do it for too long.

The temps have cooled off radically in Indianapolis. 75F - 77F is predicted for Monday through Wednesday. Unfortunately, I've been tied up with home improvements lately and haven't been able to ride much.

Because of asthma, I have more trouble riding in cooler temps than I do in the heat. I've ridden in 93F temps this summer, but I won't ride when it's 60F or under as I'll start wheezing.

My preferred shorts and t-shirt level ride is 55-65 degrees Fahrenheit. If it is 80 degrees or more I usually find something else to do.

I was out Thurs afternoon and my Strava ave was 90F. It was pretty tiring with the wind also. Here in the tropics, it's not so much the air temps, but the direct sun that bakes you. We made it through our second "Lahaina noon" (the day the sun is directly overhead at local apparent noon -- 18 July for Honolulu) so things will gradually get better.

It is unless you wait until dark.

Heat exhaustion etc...NO FUN and I've driven myself to it.

Today was a cool one. Got to ride's end around 11am, and it was only 97º. During Thursday's outing, the mercury peaked at 109º. Too hot to ride? I don't know what that means. I live in inland SoCal, where apparently some people forget that it's a desert. It tickles me to see the folks who don't leave the house if it's above 80º. I wouldn't get to ride about 5 months of the year.

I'll ride 364 days of the year, hot or cold, rain or shine. I've never managed to get time to ride on Christmas Day, so that's my default "always off."

Here. This was last week. Only 97 today, I went out and did 16 miles. California summer.
