Well its been to hot to ride much during the day with temps in the high 90s/low 100s, so I have been night riding. Practiced from 10:30, until 11:30pm. I sure have more endurance at night.
That’s what I do most nights. It works pretty well as long as there’s enough light where you’re riding so that you can see bumps and rocks and stuff.
Come to Australia, its freezing cold here. 
Now you gave me this mental image of swarms of migratory unicyclists riding from one hemisphere to another.
Can you tell me how to get rid of it too? 
I’m like that with running; unicycling in the heat doesn’t seem to bother me too much though. (Heat = 90+ degrees.) 
SAME! I hate running in the heat (I’m pampered and spoiled from using a treadmill during the cold Wisconsin winters), but I really don’t care what the temperature is when I ride, as long as it’s above freezing.
Ride to your nearest country perhaps. 
Yeah it’s even too hot for me at night here near Philadelphia.
I went out and rode for 15 minutes at 11:30 pm and came in drenched in sweat, had to change my clothes before I sat down again.
=(
Don’t have a suitable unicycle… though I think I could get one for my way back from czechia, there’s a good maker of penny farthings there.
Maybe he could sell me a penny without the farthing…
Only 1 way to find out then. 
lucky…the high’s here are 105-115 lows are barely in the 80’s…I’ve grown use to it lol
ABOVE freezing? The only thing that matters for is if you’re practicing tricks and such and the tire gets stiff from the cold.
Give me twenty below any day, but I can’t stand the heat.
That’s what lots of seasonal athletes do, like skiers. One of the nice things about unicycles is that they aren’t dependent on a frozen environment or other limiting factors. Though riding at night can sure be a relief, especially from humidity.
Of course there’s a big difference between Road riding, for example, and practicing Street. My personal record was riding home from work (8.2 miles) when it was 107 degrees (f) out. But I wouldn’t be practicing tricks in that!
I’ve been riding in the Dallas area during the late afternoon, when temps are above 100 F. It helps that I usually put ice in my Camelbak, so that I’m constantly sipping ice water. I just accept that I’ll be getting sweat-soaked, and change/shower when I get home.
If you can find a suitable shady spot, practicing tricks in the heat isn’t so bad. It might even be easier to stand than a Coker ride since you can avoid direct sun.
