Where I live, there are many open areas with a lot of wind. I always try to plan my route carefully using weather information (e.g., avoid head winds when possible).
I have found, however, that local weather information is not accurate. For instance, headwind is often shifted 10-15 degrees. For example, if the weather info reads north-west, it often feels like north/north-east.
Now, I looked around and it seems that wind is very erratic and there is a lot of local wind variation. Especially where I live, there are a lot of intermittend wind bursts.
Thus, I am wondering: are there devices that measure wind that you could take with you on your bike? I would be interested to plot measured wind strength alongside my ride information.
