The future continuous tense isn't taught very much in English classes but, in fact, English speakers use it a lot. The future continuous tense expresses action at a particular moment in the future. The action will start before that moment but it will not have finished at that moment.
The future continuous is made up of two elements:
the simple future of the verb 'to be' + the present participle (base+ing)
I will be meeting David tomorrow.
I won't be working on Monday.
By Christmas I will be skiing like a pro.
This time next week I will be sun-bathing in Bali.
