Personally, I think Federer and Nadal are more likely champions, while Hewitt has the form and pedigree to spring a surprise, but Andy could do it and I have every confidence in him.
The provisional temperature for this spring goes against recent form for the season, forecasters said, with eight of the past 10 years seeing warmer than average springs compared to the long-term (1981-2010) average of 7.7C.
