Future with going to

going to has 2 main uses in English:

1. Talking about future intentions, things you want to do in the future but you do not have a fixed plan or arrangement yet:

‘I am going to visit my grandparents sometime this weekend’ (there is a kind of plan but the time is not definite yet)

‘I’m going to start going to the gym’ (I want to do it but I haven’t sorted out my first visit or other things like membership etc.)

You can say that going to is used for plans which are not so serious yet, ‘semi plans’.

2. Making predictions about the near future based on visual evidence that we can see now:

‘He is going to crash if he continues driving so fast!’

‘You’re going to get sunburnt if you don’t put any sunscreen on it’s so hot!’
