The wind has its seasons...

“For example, the wind has its reasons. We just don't notice as we go about our lives. But then, at some point, we are made to notice. The wind envelops you with a certain purpose in mind, and it rocks you. The wind knows everything that's inside you. And not just the wind. Everything, including a stone. They all know us very well. From top to bottom. It only occurs to us at certain times. And all we can do is go with those things. As we take them in, we survive, and deepen.”

― Haruki Murakami, Hear the Wind Sing

Windy everywhere today (though the rest of northern Europe seems strangely calm... Reminds me of headlines from times past: "FOG IN CHANNEL, CONTINENT CUT OFF"). The 3-4 m/s minimum turbine turning wind speed appears to be achievable across the whole of the UK.
