The question is not as dumb as it sounds at first. I have spent a lot of time working in the yard since I was laid off a month ago. I live outside of Boston so the weather is usually still a bit chilly this time of year although it can be quite variable. For the past 2 weeks, the weather has been in the low 50’s - low 60’s during the day and mostly clear and sunny. I have worked outside for several of those days with just a short sleeve shirt on. My pasty-white Anglo skin didn’t even flinch. However, yesterday, the temperature rose to the mid to upper 70’s. I worked outside for about 2.5 hours and got burned to a crisp on the back of my neck and my face got mildly burned as well.
My question is:
Why did the air temperature matter? April sun is April sun right? The temperature is determined by warm and cold fronts moving through the area. Tomorrow, it is supposed to be in the mid-eighties. I know that I will have to wear sun screen or I will get fried. Why is this different than if tomorrow were 62 degrees and clear?
