It has been too cold to boil outside after dark the last few days so
was planning to enjoy the sunshine and boil saturday afternoon but then
it hit me, will brewing in the sun skunk my beer?

The skunking stuff (forget what compound it is at the moment) is
fairly volatile, IIRC. Basically, it's only really an issue once
you get the beer into a container (carboy, or even worse a sealed bottle).
I don't think you'll have any issues with it during the boil. The sun
and hops might react a bit, but any negtive effects will be boiled off,
so there's no permanent damage.
When I do all-grain batches outside, I almost always do it during the day.
I've never noticed any problems.
John.

Never thought about it before? I've never brewed at night, no skunked beer
yet.

I've boiled in the sun before, it didn't seem to have any adverse
effect. I think sunshine is only dangerous during and after
fermentation?
Also, speaking strictly as a denizen of snowy central NY, it's never
too cold out to boil.
:-)
(can get a bit windy, though...)

If I remember correctly, the skunk taste/smell in beer is caused when
ultraviolet light causes a reaction that turns the hop humolones into
something called mercaptans by either adding or removing (I forget
which) an OH to the molecule. These mercaptans are extremely volitile
just like hop aroma, and should boil off very quickly. I woudln't
worry at all about boiling in direct sun light.
