Dead frog in pond

 We've had very hot weather for a month and no rain. Today, I found our pond frog dead. Full length  spread put at the side of the pond, like it had been sunbathing and fried. Is this possible? Why would an adult frog die in a garden pond? Pond is 2.5x2.5 m, full of aquatic life and oxygenators,  frog been there for over a year. I have images, don't know how to attach them
