We lived in Dinuba, CA a total of 3 years. We relocated to Dinuba to be closer to my new job in Fresno, we were not prepared for how things would be. There was simply not much to do in Dinuba. It is a small city, and moving there with my wife and two kids, left a lot to be desired. Sure you have your standard Walmart, Best Buy, and a few grocery stores, but aside from that, there just wasn't anything to do.
The summer weather can be very brutal as well. With temperatures exceeding the 100s easily. So make sure you plan plenty of fun outside water activities to try and beat the heat! One thing we did enjoy during the summer time though, was the farmers market. Being so close to Fresno, and other farming areas, it was very easy to get fresh tasty produce.
All in all, I don't think we would ever want to move back. The city needs to do some major improvements to increase the quality of life while living in Dinuba.
