Very much so - although the new grass (turf) I had fitted in April did really well for rain in the first few weeks, the long dry spell caused it to begin to look faded and for the individual squares to be seen. Should have used a hose on it.
As it is, my rain gauge measured 77.4 mm (about 3 inches) of rain up to 9am yesterday - a good soak over 3 days.
