Summary:

"Going to" is used to express:

1. Predictions based on what we sense. These are usually imminent:

"It's very cloudy. It's going to rain".

2. Intentions or plans:

"We are going to travel to India in the summer!"

*note that if there have been any arrangements, then the Present Continuous is more suitable, especially if the action is imminent.
