What if Summer and Winter came together

What would happen if the Summer weather and Winter weather happened in the same day? If you think about it, it would be quite astounding. In the morning you would be able to construct a snowman and enjoy that nice mug full of hot chocolate afterward. By the afternoon it would start getting warmer and you would go swimming or sit on the beach with a nice book. For the girls who change they're clothes this would be the perfect excuse. In the morning hours you would need a coat, pants, gloves and mittens, in the afternoon only shorts and a t-shirt is permitted.On the other hand it would be extremely confusing for the environment. The hibernating animals wouldn't know whether to hibernate or not. The could animals became aggravated and start causing havoc in the society, because winter and summer in the same day is an unnatural occurrence. The fruit wouldn't be able to grow to the fullest capacity and we wouldn't be able to enjoy the flavours of our favourite fruits. Summer and Winter in the same day would be a cool thing, as long as the pattern didnt last too long.
