Hot weather and the grass

I am battling to cut both lawns in this intense heat. I have cut the front lawn but still have to do the back lawn.  Later, I think this heat will break and we will get a downpour. Off to do the back lawn now.

UPDATE 1530z:  Both lawns cut now, but the grass is becoming brown with the heat.  Both front and rear lawns need a good long soaking! A good storm with lots of rain for a few hours might help. Watering with a hose really only makes the surface damp unless it is done for a long time. Even in the driest of summers, lawns seem to bounce back when real rain does arrive.

UPDATE 2048z:  Watered parts of the front grass for more than 30 minutes as well as the flowers. Wonder if the dry patches will recover?
