The show must go on - even if the weather is at an extreme! Like your everyday mailman/lady, K-Pop stars will dance and sing, rain or shine, and make sure the performance goes on successfully until the very end.�

However, some of these weather conditions are so insane it is a surprise that these groups were even able to finish performing! Check out the list of idols who pulled through in these inclement weather conditions.

SISTAR�

��

SISTAR have suffered from a few accidents here and there in the past, but this rainy and slippery stage was a disaster waiting to happen. Luckily the girls regained their composure and laughed it off but the weather conditions definitely effected their singing.

G-Friend�

�

Speaking of slippery stages, here is the famous stage that brought G-Friend to popularity (alongside their catchy song, of course!). The girls looked like bowling pins falling left and right on stage, with member Yuju making most of the faceplants.

But this wasn't the first or the last time G-Friend was caught in the rain! Pelting them like bullets, the harsh rain didn't ruin their parade as they carried on with their cute performance below.

Oh My Girl�

�

Just like G-Friend, Oh My Girl were a victim to rainy, windy outdoor conditions. Like performing on a slip and slide, the girls did their best to maintain their balance and put on a show. It seems it really was a "Windy Day" for these girls. (Yes, I just did that play on words!)

Red Velvet�

�

Believe it or not, the girls of Red Velvet performed for the 'Gayo Daejun New Year's Special' in -1 degrees Celsius, which is about 29 degree Fahrenheit. These girls must have felt "Dumb Dumb" and numb numb while dancing on stage. What is more shocking is that you can see their breath in the frosty air.

BTS�

�

Sadly Red Velvet were not alone as hit boy group BTS suffered in the same cold. They can be seen here practicing in heavy coats before the New Years performance. Just like Red Velvet, they are visibly cold, shivering, and their breaths fog up in the cold winter air. These boys really do need a "Fire"!

Nine Muses�

�

Nine Muses can be seen dancing and performing "News" in this frigid rain and wind. It was so windy that it blew off member Kyung Li's hat and she fell down along with it on the slippery stage.

f(x)�

�

Another rainy disaster (practically a monsoon), the girls of f(x) are soaked to the bone as they performed "La Cha Ta" in this extreme downpour. The water is flooding off the stage and it is amazing that they didn't slip and stumble. It is even more shocking that the flimsy, shaking stage could support their weight as well as all the water.

TWICE�

Possibly the worst one yet, the sweethearts of TWICE can be seen showcasing their individual talents and dancing in the freezing snow at a mini fan meeting. (Check the 11:00 mark.) While they have coats on, underneath they are shown wearing short skirts and shirts with little to no coverage. Fashion really is pain, I suppose.

However, snow wasn't their only problem. The girls fell victim to the terrible summer rains as they performed "Like OOH AHH" in their famous short and sexy outfits.

2pm

The handsome boys of 2PM were caught in the intense, heavy rain during their 'Open Concert' performance along with other singers like Crush. Although soaked, 2PM continued onward with their complicated dance routine in the downpour.

Girl's Day

The rain continues to be everyone's enemy but, in this case, it turned out to be Girl's Day's best friend! While the conditions are terrible for any idol to perform in, the girls were able to look even cuter despite being completely drenched in the cold rain.
