I can't currently measure the Contis myself, since I swapped them out after 8k 
miles (with rideable tread left!) in order to give the GB's a go. However, a 
survey of old forum posts suggests that other folks have measured them at 
~34mm, so they might work for you. Note that rim width will matter: the same 
tires mounted on wider rims will measure a little wider on wider rims than on 
narrower rims.

Would it be possible to measure the actual width of the Conti's?  I have 
two bicycles that can take  35mm +/- a mm or so with fenders and with a bit 
of fettling probably a tad more, so tire threads are excellent information 
for me.  I've read the Vittoria Randonneur Hyper tire is also well regarded 
and comes in sizes of 700 x 32/35/38.  Would love to know actual widths of 
tires as some manufacturers seem to be flexible in their measurements.

Currently I'm running Kojaks 700 x 35 that measure 700 x 33 give or take 
0.5mm according to my digital caliper.  

I've used Marathons in 700 x 35mm and 40mm (fender-less on the 40mm), but 
suspect they were narrower than stated on the sidewall.  They seemed to me 
to be excellent tires for loaded touring and general rough abuse and roll 
well enough.  Good puncture protection until they wear out, which takes a 
long while.

Hey there Peter - 

In general a larger tire at a lower pressure will give the best footprint.  
More footprint = more grip.  Over the years, I've ridden a pretty wide 
variety of tires through the rains and I'm not really sure one stands out 
as horrifically bad.  Wet weather riding really does have a lot more 
variables which rank higher in my book.

- Is it the first rain in a while?
This is probably more of an issue for those of us in CA or areas where 
there are extended dry periods between storms.  The first (and sometimes 
second and third) rains bring all the oils out into a film which can make 
you feel like you are on ball bearings while wearing roller skates. Or, you 
tap the brake and are down before you know what hit you. The first rains 
always put me on "DANGER WILL ROBINSON" alert, as other vehicles will also 
be having trouble.  

- Metal
Wet metal is bad. Construction plates and any kind of train tracks should 
always be assumed to be extremely slick.  Avoided if possible. Here's a 
good time to just get off and walk if not. Always cross tracks at 90 
degrees if they are wet.  Just saying.

- Thick paint
Those big crosswalk stripes.  Road lane striping.  Those always seem to be 
adhesion erasers long into the wet season.  The big issue here is that 
those often appear where we are trying to make turns.  

- Confidence 
If you ride loose and keep your head up, you'll be surprised what you can 
recover from.  A bike that starts to slide one way can often be brought 
back just as easily.  A lot of it has to do with keeping your weight off 
the front end of the bike and really trying to steer from your hips.  (not 
unlike riding in deep sand, but without any of the sluggishness that you 
feel when doing that).  A bicycle will not hydroplane like a car, so you 
actually maintain pretty good contact with the ground.  Once you have a few 
rides on non-greasy (after the initial rains) pavement, you'll see you do 
actually adhere pretty well.  The things that work against you are oil, 
metal and paint. Obviously, you don't want to really "push" things if you 
don't have to, but it's important not to lock up or ride tight.  I do try 
to keep my body a bit more centered over the frame, but the bike itself 
actually works pretty well in wet conditions. 

That being said, a round profile tire with a predictable behavior as you 
lean is my choice.  It should not surprise anyone that the Jack Browns fit 
that bill well for me.  Since I ride those most of the time, they 
don't/won't surprise me when I lean, and they have a plenty sticky compound 
if I'm not doing something I shouldn't be doing.   I will agree with 
Patrick that Fat Boys (and some other tires from that same company - which 
I actually got comped (and they don't make anymore) ) were not known for 
wet weather behavior.  

I will also say that riding fixed in the wet weather will give you a 
heightened sense of adhesion.  

Hope that is of some help,

Peter:

Same as per others; as wide a tire as you can will take the hits of poor 
street surfaces. I put on some 700 x 37 Schwalbe Marathon Plus 
Smartguard tires and have been well impressed. I'm a daily commuter and 
have had no flats for 14 months despite some pretty awful pavement. They 
felt  a tad heavy-ish and had a really narrow band of optimum inflation 
range to me initially, but their durability has been astonishing, the (lack 
of) tread wear particularly. 

I admit and accept the performance compromise but revel in their durability.

I have no problem commuting in the rain on my nearly-treadless Jack Browns 
(700 x 33 1/3), the only thing I do out of normal is drop their pressure 
down to 45 psi, so they have more contact and more cush.

Hi Peter
 
I ride commute  regularly (spring,summer,fall)  on Panaracer 
Paselas...either 26"  X 1.5 or 700c X 35mm @70-80psi. These have a round 
profile and a nice chevron-type  tread. If your Cannondale is a touring 
bike , the 700c  size might work, but how fat a tire you can use dpends on 
clearances and fenders, etc.They're quite tough, and not excessively heavy, 
especially if they have the Kevlar and not the wire bead.I've used both 
sizes since, oh,I'd say at least 5 years. I commute on an X0-1 with fenders 
if it is raining when I leave or a PX-10 which, with the 700 fatties, 
doesn't have any clearance for fenders. For regular mortals such as you and 
me, skinny, slick tires are not confidence-inspiring , to say the least.
 
Obviously,  rain,mud, gravel,wet leaves , etc dictate a change in riding 
style...but I feel these tires have not let me down. If you're commuting 
regularly, I'd say tires are not a good place to economize
 
Other people on this list will have other excellent suggestions. I've heard 
lots of good things about Schwalbes ; there are models equivalent to what 
I'm using. I've heard they're durable...and some models can be a bit spendy.
 
Good luck
