Did you ever try using the NOAA's weather.gov with your smartphone? Its not 'real time' for your exact location, but its
free so it can't hurt to try it out. type in your zip code or location in the upper left and it'll come up with a general weather report for your area, then look on the middle of the page on the right and click '3-day History' for most recent weather data (including general wind speed) for your area. The reporting can be anywhere from every 15 minutes (in my suburban area) to every hour. Also below that '3-Day History' you'll see 'Mobile Weather' which isn't too accurate, but the 'Hourly Weather forecast' right below it has some good graphs that project into the future. The display will be small so you'd have to stop pedaling to check it. Remember, its free so worth a look if you're not too concerned with exact data.
