    Why is it during the day time it could be 3c out but in direct sunlight it feels much warmer despite it being 3c outside?

    That is because that air temperature is always measured in the shade. The temperature in the sunshine can vary depending on the strength of the sun at any given time and so is not an accurate method. Shade temperature is much more consistent, no matter what time of the day or year it is.

    It's because the sun emits infrared radiation in the form of short wave energy.
    This is why it is warmer in the sun than in the shade.

    Then continuing on from that a solid (You) absorbs the energy from the sun quicker and easier than a gas (the air).
