Vettel clinched his ninth pole position of the campaign at Spa on Saturday afternoon, easily quicker than the chasing pack in the wet conditions. Vettel's best was a 1:48.298, 0.432s up on McLaren's Lewis Hamilton.
"It was a difficult session all in all," he said. "Q1 and Q2 with the tricky conditions, and the circuit drying up very quickly and it being tricky on inters - the main target was to get through.
"I didn't feel comfortable right in the beginning, but in Q2 we made a big step forward. I rediscovered Spa in a way and found some better lines than all weekend and in Q3 we were quite sure it was dry (enough for dry) tyres but also quite sure if it didn't rain it would be down to the last lap."
But while Saturday may have yielded Vettel's ninth pole, it wasn't an easy outing for the reigning World Champ, who admits his lap time was also down to getting the timing just right for when the track was at its best.
"I wasn't really happy yesterday or this morning, but we did the right steps to come back and especially when it was drying up. If you would put your money on that around here, all in all we got the timing right, especially in the last qualifying session it was feeling good and we got it together all the time.
"I was trying to make my way around in the last two laps [in Q3], trying to get temperature in the tyres, trying to push as hard as I could.
"Lewis was right in front of me a couple of seconds ahead and I saw him locking up, last thing. I was happy with the car towards the end in the dry and it seemed to get quicker and quicker.
"Not an easy session with conditions changing and right after it finished it started to change again, but here, as we saw today, anything is possible."
Looking ahead to the 44-lap Belgian GP, at present the forecast is for a dry afternoon, however, at Spa the weather is known for changing rapidly.
And it's because of that factor that Vettel reckons a lot could happen come Sunday afternoon.
"It is one of those races, anything can happen from start-to-finish, we will see. The best forecast around here is to look up and see what is happening!
"We had a good balance in the end in the dry, the beginning of qualifying I didn't really feel comfortable. Even in the wet we found direction and it should be ready for tomorrow, it is a long race so I am looking forward to it."
