Windfinder isn't a forecast. It reads professional anenometers in real time. It uses that data and other weather information to predict forward. Obviously, the further forward you look at the prediction, the more likely it can have errors, but at the present time, it's 100% accurate. The real-time data means that you don't have to go out of the house with your hand-held, so you can use your phone while it's connected to the house broadband. Incidentally, you can get all these things for the iPad too. Put your iPad to work. It can do more than Facebook and Skype.Interesting specs Dan. Thanks.
I bought the anemometer because sometimes I can't believe how hopeless the forecasts are when I am out on the bike. One piece of software in particular made me give up on it when it predicted 66 mph winds and it was actually 6 mph. Usually though I suspect that the wind is higher than is being forecast and I want to check it. I am actually interested in the boundary layer effect as that is what I am riding in. I was pushed off the road once on my motorbike by the effects of the wind in a whistling around a hill. I was once lifted off my feet here by the wind coming around the corner of a building, and at 85kg I am not exactly light. Windfinder sounds interesting nonetheless, and I am sure that it is useful when a mobile signal is available if outside the house.
A local reading with a hand-held anenometer is as good as useless, because you get different anomalies depending on which way the wind is blowing and whether there's hills and troughs. if you know the prevailing wind, you can estimate what the effects will be along your rides. The main thing is the speed of the prevailing airstream, which tells you whether it's windy or not and the general direction of the wind.
I have a hand-held anemometer for my boat, but it's totally useless because the airflow has to accelerate and change direction to go from the flat sea over my boat where I'm sitting. The one on the masthead 35ft up is totally reliable and tells a completely different story to the handheld even when I'm standing on the coachroof with it above my head.
Any comments on the photos?
