Just fyi, it's hard to gauge wind speed with any accuracy so after I downed my P2 on a windy day I searched for a wind meter (anemometer) and found this little guy. Works great and it's very small. It's $35. La Crosse Technology EA-3010U Handheld Travel Anemometer with backlight and included Neck lanyard by La Crosse Technology: http://www.amazon.com/dp/B0002WZRKE/ref=cm_sw_r_udp_awd_EZgKtb1J8JKM9 Hope this is helpful. As a reminder, the DJI guide says don't fly in winds >13-17 mph.
