30C isn't very hot. With plenty of water, grass does very well in heat and can, in fact, experience its greatest growth under very hot and humid conditions. Here in Central Illinois, we're at around 95F (35C) and some of our grass is turning brown and withering - but we also haven't had any real rain for at least two months. If we were able to water the lawn well, it would be doing great.

Your grass should fill in nicely over the summer and early fall, but it probably won't actually be thick and lush for another year or so. Overseed in the fall and fertilize the lawn - that will do it a lot of good.
