Heavy rainfall made for treacherous conditions in the first ever Korean Grand Prix two years ago.
Conditions seemed little different when the teams returned for Friday practice last year, although the weather cleared up by race day.
This year drivers can look forward to good conditions throughout the weekend. All three days are expected to be warm with temperatures exceeding 20C.
The wind will pick up as the weekend goes on, with a stiff breeze from the north expected on race day.
Shadows will be lengthening at the circuit as the race draws to a close. The Grand Prix starts at 3pm local time, with sunset expected three hours later.
