I will go to the beach next Saturday, so I want to know the weather at the beach next Saturday.
I am trying to describe this without referring to the specific time "next Saturday". My examples are as follows.
- I want to know the weather at the beach when I go there.
- I want to know how the weather will be at the beach when I go there.
I think the second one is grammatically correct, but I am not sure whether the first one is correct. Specifically, I think the first one needs a verb such as "expected" before "when" because "when" cannot modify the noun "weather".
