So, there you have it. I did say it was a mixed bag.
What you would have noticed is that Pollen has now been dropped from our forecasts until next year, and in its place, I've now included the Dew Point forecast.
So what is Dew Point I hear you ask.
Dew is the small droplets of water that appear on objects such as leaves or grass in the morning or evening due to processes of condensation.
How does Dew form?
Dew forms when the temperature of a surface cools down to a temperature that is cooler than the dew point of the air next to it.
When this happens water vapour will condense into droplets depending on the temperature.
The temperature at which droplets form is called the dew point.
When surface temperature drops, eventually reaching the dew point, atmospheric water vapour condenses to form small droplets on the surface of grass, leafs of trees, damp looking pavements yet no rain, and what forms on your car for example, yet again no rain overnight to make it wet.
Hope that explains it enough for you to understand. Do ask any questions if not sure.
Catch you later..
