Here is something I wrote that was geared towards switching from winter to spring.
We had a lot of people bemoaning the winter cold and I wrote all these to help and
combat that. We used this in the Ostara 2011 rite posted on this website but split it to bookend the ritual.

Hail to thee Skadhi! Lady of Winter’s whites,
Your call have we heard across our homes, On these many cold days and dark nights.

Hail to thee Skadhi! Wolf-maid and Goddess of Bow,
Your touch have we felt all these long weeks, our lives filled with your snow.

Hail to thee Skadhi! Mistress of Winter’s fun
Thrymheim beckons your loving hand Your duty here now is done.

Well have we rested
Well have we paused
Well have we met those we hold dear

Well have we thought
Well have we learned
Well do we know what Season is here

Hail to thee Eostre!  Lady of first blooms,
Your touch do we crave across the land, the stirring of Nerthus’ womb

Hail to thee Eostre!  Maiden and Goddess of Youth
Your smile is needed to lure the sun, to give a promise it’s truth

Hail to thee Eostre!  Warder of Spring
Your love now shines to warm the earth, we give hail for all that you bring.
