Brown lawns

We have just returned from a week on the Isle of Wight. Many parts of the lawns at our bungalow look dry through a lack of rain. There was a thunderstorm here a few nights ago, but I suspect little rain fell.
 
The lawns usually bounce back in the autumn, but this year everything is about 4 weeks late flowering and the lawns have actually remained green for longer. I think summer is finally catching up with the lawns though and I expect they will remain dry for several weeks now unless we have lots of rain or I water them furiously. If lawns are watered they need a lot of water that goes through to the roots. In many ways the grass is better left.  In order for them to look decent and keep the weeds down, it is tempting to cut the grass too short.
