tropical

I'm a little stuck... Click here to teach me more about this clue!

'very hot' is the definition.
(in the tropics)

'up-to-the-minute is about right' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'about' could be 'ca' (short for circa) and 'ca' is found in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
This explanation may well be incorrect...

'for' acts as a link.

Can you help me to learn more?
