Are You Suffering from “Summer Penis”?

summer penisThe heatwave hitting areas around the world (a friend of mine said it was 33C (91F) in Ireland the other day!) has a lot of people hot and bothered.

However, unlike the normal complaints when the temperatures soar — men are reporting an interesting phenomenon…


What is Summer Penis?

Summer penis is a phenomenon where men claim their penis appears to be bigger, thanks to the heat.

Now, this isn’t the same as summer penile syndrome, where guys get painful and itchy bites on their package. Instead, this phenomenon is all positive.

A Reddit thread had a user asking if other guys had experienced their dicks being larger in the summer and smaller in the winter.  Lots of guys chimed in and agreed. The theories began.

Is it the warm weather creating better blood flow?  Is it just the body trying to regulate temperature?

Orlando urologist Jamin Brahmbhatt confirms that the penis can change in response to temperature. He stated,

“Also when it’s hot outside, you may take in more water, which may in combination with the sweating make it appear like your body or skin is bloated. And that may give you the perception that things are larger.”

Dr Sarah Jarvis, GP and clinical director of, said,

“Technically when you’re hot, as well as when you are excited, then your blood vessels may expand. When blood vessels on the surface are a bit bigger then things are going to look a bit bigger. But your penis is not growing, it’s just your blood vessels growing slightly larger as a way to reduce heat. And no, it’s not going to make you perform better either – when you are erect your penis is swollen to the max anyway.”

Basically, it’s the opposite of what happens when you jump into a cold pool and you experience shrinkage.

So, what do you think? Have you experienced Summer Penis?

  1. I live in Yuma,AZ and if there was such a thing my penis would be king.
    On my best day it’s 6″ long with a 1.75″diameter. I’ve been told it’s textbook in appearance. But no one has said it gets bigger in the heat.
