I did it in the summer.
There are no slippery holds on the route so it won't matter.
I actually prefer a bit warmer. You can't feel your hands when it is too cold.
Just make sure that you head down in the afternoon.
We used to head down there around 9am if I recall.
I think the sun moves off the wall around 12-1.
The sun will be in your eyes on the last deadpoint in the afternoon but I don't think it is until 3 or so.
Let me know when you head down. I will give you a belay an my exact beta again.
Here is an early on attempt. It should help you remember the moves.
