<p>In this case, as it is an area that it is almost constantly cloudy with high humidity, temperature is varying just a little bit, and except the first day of the period, it seems that there is no relationship.

I know this is an old post, but i asked the same question about it getting hotter later in the day and it brought me here. I dont have any facts to back up my claims either but yes! I always paid attention to the weather when i was younger and i swear it is getting hotter later! I remeber i would wait till 2pm or 3pm to leave instead of leaving around 12 noon because that was when the sun was at its "highest." I sure would like to find info that can substantiate my claim

It's important to rely on actual temperature data to make claims of temperature change. In regards to this question:  1) hopefully you aren't basing this on how you feel inside your home (which doesn't reflect outside temperatures), and 2) our tolerance for heat worsens as we get older, so it might feel hotter when really we are just feeling the effects of aging.

(Asked by: username_0 on 2023-05-27)

I have lived nearly my entire life in the same home. It appears to me, the hottest part of the day is getting a bit latter in the day. I tried doing a Google search, but I did not see any links that would support this idea. Also, I do not have any hard data to back up my claim.

I am thinking there is more CO2 in the atmosphere now, so it takes more time for the sun to heat it up and therefore the hottest part of the day is latter.

Here are some links that I have looked at:

It is not as simple as this, as the temperature is not related just with the CO2 or sun radiation but: some other gases, moisture, wind, cloud presence...

One thing is the real dry temperature, that you can get from a weather station and another subject is "feels-like" temperature, that takes in account water pressure, wind... It is more close to what you can feel as temperature.

For the real dry temperature, main actor is sun radiation, as soon as you get more radiation, you are increasing temperature as all the gases at the atmosphere become excited by radiation. As soon as you reduce radiation, temperature is becoming low.

I recomend you to check by yourself. There are some more "free" webpages when you can get weather data as solar radiation and temperature and check how they are changing along the day. I used [this link](https://www.visualcrossing.com/weather-data) to get data from different places at different latittudes, as solar radiation, on the same days, varies in value and time.
