Can the heat cause an otherwise good inner tube to fail?
Reason I ask is I'd ridden about 20 miles this morning and was sitting by my bike taking in the weather for about 10 mins when the tube in the rear road wheel went pop then pfff.
The heat is the only explanation I can think.of.
Any tube can explode if it has too much pressure in it. Hot tyres = increase in pressure, but you shouldn't be needing to have a tube near its upper limit anyhow.

What heat.... if your tyres are up near the max and you leave them in the sun then maybe but people do manage to ride in much higher temperatures and with much higher temperature variations. Never saw more fails in those places

How old are the tubes? Could be dirt inside the tyre wearing the tube.
I’ve witnessed self adhesive patches give up the ghost at ~26degrees c.
Did the valve fail where it joins the tube?
though warmer temps lead to higher pressure that shouldn't burst a tube...its the tyre carcass that is taking the force due to air pressure and not the tube. The tube is compressed against the inside of the tyre. And in any case the pressure increase due to the sorts of temps we've seen today is very small, the pressure difference due to a 8 deg C temp increase is only about 1.5psi, so there is no way in the world the warm ambient temps have caused your tube/tyre to blow. It should be easy to spot if it is a previous puncture patch.
I thought I'd replied to this yesterday with a few more details.
tyres are 28c run at 95psi, the innertube 'blew' nowhere near the valve and wasn't near a previous repair.

Well if it's temp changes then you better let the Giro, TdF etc know along with the ones that go to hot places too
