ELI5 - How can the sun can be out, no clouds in the sky, and it's 83 degrees, the next day, same situation and it's 101?

Today was a pleasant day in Pasadena, but i noticed that the sun was beating down on me, but it felt pleasant. While the last few weeks, the sun has been beating down and it's been unbearable! Why do the same circumstances lead to different temperatures?

Weather is being imported from the areas around you all the time. Hot airs can blow in from elsewhere, a day in the sun can cause a previously cool body of water to heat up some and provide less of a mediating influence, etc.
