Racing around the streets of Monte Carlo for the very first time, Daniil Kvyat admits the rain did not help his cause.
Unlike the rest of this year's rookies, Thursday's running in Monaco was the very first time that Kvyat experienced the tight twisty street circuit.
Putting in 37 laps in the morning, he was 18th quickest before improving to P12 in the afternoon.
However, the rain that left the track wet for FP2 meant the Toro Rosso driver was only able to complete 13 laps on a track where he really needed all the running he could get.
"I enjoyed driving here in Monaco finally and it was a good day overall, in which I was able to learn the track quite well," he said.
"Those were my instructions from the team, who told me to go out and do as many laps as possible.
"Of course, the rain that made the track wet for some of FP2 did not help so much, but at least I have tried the circuit in both dry and wet now.
"The results are obviously not very representative because of the tricky conditions this afternoon.
"We will now look at all the data between tonight and tomorrow to get the best out for Saturday's qualifying and Sunday's race."
