Because it seem all rides are both uphill and against the wind, there have been various wind speed indicators available for cyclists. I bought a Davis Instruments WindScribe http://tinyurl.com/l3wpe for just that purpose and mentioned in a response to another post my curiosity about the weather worthiness of that unit. The total absence of responses prompted me to email tech support at the company from whom I got a prompt reply reassuring me that not only is the unit weather proof, it will even float. I'm guessing that if during a rain and water droplets accumulate within the ultrasonic sensing tube, you might have to shake or blow it out to regain measurement accuracy.

Piggy backing myself:
I just got another email from a different company representative regarding the WindScribe stating: "If it gets a few drops on it that is fine, but if it gets soaked that is not good. It is not Water Proof." I don't plan to be out in a soaking rain, at least not here in San Diego, but it's something to think about for riders in other areas.

If you want a really good all weather instrument, try a Kestrel. Waterproof and floats as the Nielsen-Kellerman folks originally made these for boating. Google Kestrel Wind Meters.

I had one once, was a hand held, is there a way to affix one of them to the handlebars to allow both hands on the grips and still see the readout LCD?

The Kestrel unit I have comes with a base that has a standard nut for attaching it to a tripod. I use it with a standard tripod to set up a miniature weather station at study sites. There are plenty of handlebar mounts that have a standard tripod mount.
That being said, I doubt I would ever mount it there. The instrument would stick up 8 inches or so. Below is a link to a Kestrel in its mount attached to a mini tripod. http://www.ambientweather.com/kepotr.html
Just imagine that standing up from your handlebar! Perhaps if you had a secondary accessory bar that provided space further away from the handlebar, it would be tolerable. For me, the additional data just isn't worth the additional hassle.

I initially got the WindScribe because its readout is topside and the whole thing is low profile, the weatherproofing question came up later and hasn't yet been an issue. It's like the terrestrial (wheel sensor) speedometer/computer, just another curiosity to distract attention from the road, for an old pleasure class geezer, who always wears his helmet.

If pleasure is your goal why wear a helmet? Oh, yeah, always carry a plastic baggie with you, if it starts to rain put the baggie on the distraction.

As an interim measure why dont you just try taping it to the handle bars to see what results you get. However I am skeptical that it will measure air velocity (the vector sum of your ground speed and wind speed) correctly. This is due to flow stagnation as the air slows down in front of an object. You would really need to attach something like a long stick to your bike and put the wind measuring device on the end of that.

As my riding is more of a pleasure quest than a scientific endeavor, there's really no need for such elaborate contraptions. Looking at the numbers is satisfying enough, with the difference between the two speed indicators (ground & air) confirming the apparent extra effort required.
