Although windows facing the West and North are desirable for houses in colder climate areas, they’re definitely one of the lesser known reasons for a hotter room. This is where insulation and window overhangs come into play. They reduce the amount of heat entering the room, making it slightly cooler by dropping the temperature down a bit.

Why is my room hotter at night?
When you refer to it being ‘hotter’ in your room at night, this probably means that it is a question of feeling warmer rather than an increase in the ambient temperature of the room in degrees Fahrenheit or Centigrade. If this is so, and ignoring the effects of blankets and comforters which I am sure you have considered, then I can only suggest that the drop in temperature outside has increased the humidity there, and that some of that water vapor has come into the house and been absorbed by the dryer air there and increased the conducted heat transfer to body and made you feel warmer.
Why do we feel hot at 30 degrees?
You produce heat. Human body always produces heat and lets it out into environment. That’s why we feel really hot at 30°C yet our body temperature is 36°C.

Your body cools based on no fewer than five different modes of heat transfer with the environment which are affected by four different parameters which can be measured by three different temperatures (which can actually be given a weighted average to yield one temperature that most accurately predicts how hot you feel…and no, it's not the “heat index" used by meteorologists so often in the summer months).
Why does my AC unit run during the day?
Also, if you had an air conditioner, it might have run during the day. This would be because the sun heats the building. The AC not only cools the air, it removes moisture by condensing it. Actually it can’t lower the temperature, until enough moisture has been removed. So an AC unit is really functioning as a dehumidifier, keeping you house dry and you “cool”.
How does air convection work?
Air convection within a building is driven by something called the stack effect - it’s the same way a chimney works.

This new air is heated and rises, and ...
