Turf is perfect in California no matter the weather conditions. We recently got out of a drought in which we saw a lot of people's lawn's slowly die over time. Not only was turf great for that time, but it also helped save water. Nowadays, we get some rain here and there, which from what I've heard, helps clean the turf naturally. Even on days when the weather is extremely hot, GST turf doesn't seem to have any issues for my customers.
