oppressive heat

I had once to travel along twelve leagues of this wearisome road, under the most oppressive heat of the sun.

Oppressive heat, dust, thirst, and the weight of heavy equipment slowed the step and caused considerable straggling.

I hope you did not suffer so severely as we did from the arctic cold that rushed in after the oppressive heat.

It was a brilliant day, the Southern sun struck with semi-tropical fervour, the air was soft and sleepy in the oppressive heat.

I know what it is to stack hay under a sultry and oppressive heat.
