Summer is Over
Jon McLaughlin f./Sara Bareilles Lyrics

Autumn never seemed this cold before
The writer is feeling colder than usual this autumn

Here I am sleeping on the floor
The writer is feeling down and sleeping on the floor

We changed just like the leaves / Outside my house / And my phone lay silent by the couch
The writer and someone important to them changed like the leaves on the trees outside the writer's house, and the writer's phone is silent, implying they are being ignored or avoided.

I remember June / Back when I met you / And your eyes were green / And we were, too
The writer remembers the month of June when they met someone whose green eyes they will always remember, and recalls feeling a sense of unity with them.

But summer is over / We were tangled in the morning sun / Felt you getting colder / And we knew that we would come undone / And it's back to my town, back to your life / Gray skies are blowing a kiss goodbye to the lovers / 'Cause summer is over
Summer is over and the writer and this important person were intertwined in the morning sun, but they felt that person slowly distancing themselves and both realized that their relationship was coming to an end. The writer and this person are going back to their respective towns and lives, and the gray skies are a metaphor for the sadness that comes with the end of summer and a relationship.

I can still see your silhouette / In the white hot sand / And I still feel your ring on my hand / And the clock was always ticking down / Behind that glass / Singing 'love, be good while you last'
The writer can still remember the silhouette of this important person in the white hot sand, and still feels the weight of their ring on their hand. The passing of time was always present in their relationship, represented by the ticking clock behind the glass, but still, the writer remembers the phrase 'love, be good while you last'

But we both knew / What we were getting into / The things we said / Sounded true
Both the writer and this important person knew what they were getting into, but they still fell for each other. The things they said sounded sincere and meaningful.

The distant innocence / We are leaving far behind / Your last words will be burning in my mind / In the winter time
The innocence in their relationship is now a distant memory that they'll be leaving far behind. The writer will remember this important person's last words, burning them in their mind, lingering even in the winter.

Well summer is over
Summer is over

We were tangled in the morning sun / Felt you getting colder / I knew that we would come undone / And it's back to my town, back to your life / Gray skies are blowing a kiss goodbye, goodbye
The writer and this important person were caught up in the morning sun but the person started to become distant, and the writer knew that this relationship wouldn't last. They will go back to their respective towns and lives and the gray skies serve as a goodbye to the relationship.

Summer is over / We were tangled in the morning sun / Felt you getting colder / And we knew that we would come undone / And it's back to my town, back to your life / Gray skies are blowing a kiss goodbye to the lovers / 'Cause summer is over
Summer is over, and the writer and this important person enjoyed their relationship during the morning sun but could feel themselves growing apart. They both know it's time for them to go back to their lives in their respective towns, and the gray skies represent the goodbye to this important relationship.
