Can I wear long sleeves at 3 1 degree?

It is more appropriate to wear short-sleeved shorts from 24 to 3 1 degree. The temperature of 24-3 1 degree is cool and comfortable, not too hot, but you can't wear long-sleeved trousers, otherwise it will be very hot and uncomfortable at all. You can wear short-sleeved shorts at this temperature. In rainy or windy weather, the temperature will drop, so it is more appropriate to keep warm and add a coat.
