Air Temperatures Here and There

I really need your help here. I went out with an amazing girl the other night and we talked about how in given area, especially at night, you can feel a noticeable change in temperature as you walk from one spot to another. I told her that I would find out why this is, but I haven't been able to locate the answer. Can you help me?

Thanks

Thanks for sharing your dating story with us! :) It really depends on where you are walking, but you definitely aren't crazy. There's a few things that go into the temperature of the air in a given area. Vegatation, materials (concrete vs. something like wood), moisture, wind and light.

So if you were walking, say between a grassy park that was just watered and then walking over the concrete sidewalk, those two areas might be very different in temperature. Also, if you were going between lit grass and shaded grass, those temperatures would also be different.

It really depends on those factors above. If you're on a street, walking by homes, you might walk by one home and feel cool but feel totally warm in front of another one. Look at their lawns. If home number one just watered the grass and the flowers, the moisture is then evaporating. This is a cooling process and you will feel cooler. If you walked then by the next home and it felt warm, the lawn there might even by xeriscaped and totally dry. So that lawn will feel warmer. If you keep walking and then cross the asphalt street, you might notice it feels a lot warmer there! The asphalt is radiating the days' heat back to the sun so it feels warm.

Also, are you blocked by the wind? If you're walking south and the wind is coming out of the south in your face you might feel cool. But then when you turn right and walk west, the wind would be blocked by homes or buildings, you might feel warmer there.

Hopefully this helps.
