      It depends on what you mean by ‘good’?
      I havnt found any research to say it rains more or is cloudier in the middle of the day in Ireland. In winter it is usually much colder and usually frosty in the mornings and evenings. It’s dark until 7am and usually dark again at 5pm. So the middle of the day in winter is usually the nicest part!

      Hi there,
      Interesting question! The weather is something that affects us all! I must admit I haven’t observed this pattern myself, but it is true that weather changes a lot during the day, as well as with the seasons. These changes depend on what the mass of air over an area is like: some air masses originate closer to the poles and are cooler, others from equatorial areas are warmer. They also depend on something called atmospheric pressure: the force per unit of area exerted on the Earth’s surface by the weight of the air above the surface.
      Basically, areas with a low pressure system tends to bring in clouds and rain-yuck! But high pressure tends to bring in clear skies and nice weather! đŸ˜‰

      I wondered about the same thing for a long time! It’s something that I noticed when I came to Ireland, and it seems to be quite common on the West coast, close to hills and mountains. As for the reason, I am not too sure… I have heard that it has to do with the sun warming the cool, humid air above the sea a few hours after sunrise. This air full of water hits the hills and condensate in the form of clouds. Sometimes, when the heat of the sun reaches this layer of clouds easily enough, the clouds will lift (it’s called the “burn-off”). Otherwise, the clouds tend to lift up after mid-afternoon, once the sun is not so strong anymore… So we end up with glorious sunrises and sunsets, and really crappy days!

      As the rest of the people noted I havent seen any evidence on whether this actually happens so I think the answer to this might actual rest in our heads more then in the weather.
      Humans are terrible at removing our biases from the patterns we see in the world. People play the lotto dispite the chance that its more likly to get struck by lightning and peolpe are more afraid of flying despite the drive to the airport in the car being more dangerous.
      In a similar way I think why we think the weather is worse in the moring and the evening is because we are stuck inside during the day looking out the window wanting to go outside . What happens then is that we only remember the weather being bad outside when we’re stuck inside and we forget when it is was actually good. This is called confirmation bias. Although it very possible that your claims are true in science we always have to be very carful about this and make sure we have hard data to back up all our claims!
