How about:

Spring has Arrived!

bahar geldi

or

bahar vardı

Is gelmek or varmak better in this case? Can the ´has´ somehow be part of this?

bahar geldi

bahar vardı - something like "ït was spring"

lets wait a native to explain more exactly

Varmak mean to arrive while gelmek mean to come. i think it´s correct bahar geldi like gabriela said. Var show excistance of something.

it was spring=bahardı (Bahar vardı is not correct in this situation) 

Evimizde hep bahar var (in this sentence it´s correct to use var)

this is my opinion.

Is this OK? Bahar var?

Yes, we say  " Bahar geldi " = Spring has arrived.

I found this on google

Bir Bahar Vardı

The way it´s used in the poem is different. The first line would translate as:

"There was a spring which told your tale to me"

I know....but all I wanted to say is - it could be "bahar vardi"...but only methaphorically

i think you can also say like that:

zamanın birinde bu evde bir bahar vardı, ama o gitti gideli herşey değişti.

KediNero

baharlar vardi?

Bahar looks uncountable to me. Actually okay, it is countable, like in the song "söyle kaç bahar oldu?" What I mean is that bahar is not pluralificable

Baharlar would only mean a girl named Bahar and some people somehow related to her:

"Baharlarla buluşalım."

in the "arrive" sense;

Bahar vardı. - weird

Bahar geldi. - better

in the "exist" sense;

Bahar vardı.  - weird

Bahar havası vardı.   - better    (describes the weather)

To me, "bahar vardı." sounds like "bahar diye bir mevsim vardı." = "once there was a season named bahar"

Why? Colloquial.

But if you´re writing a poem or inventing new uses in general, all is fair

I guess when a foreigner says it, it is weird. When someone wearing glasses and a scarf around his neck says it, it is art.

Of course, if we´re talking about a girl named Bahar, that´s a different story.

How about bahar gelmiş

Maybe ´has´ or ´have´ is not used this way in Turkish. For example if I want to say "I have eaten" in Turkish rather than "I ate".
