Hadn't really got that far in my planning. Might do it on a weekend, might do midweek. Probably end of August/beginning of September to maximize the chances of actually being able to get over the top.
I did pico veleta in the second week of Sept a few years ago - foggy and cold at the top, but still very doable. My fingers froze on the descent though.
No worries. What sort of itinerary were you thinking? I'm considering a solo midweek trip in September just now.
