Today will be a nice day if you make it a nice day. It is not necessarily the weather that makes a day nice but rather the attitudes that people have that determine how nice it will be today.
The benefits to a nice day in terms of weather are that people are more cheerful when the weather is nice. Deprivation of sunshine is commonly linked to depression.
