Let your Sims swim in the ocean on a hot summer day, bob for apples in the autumn leaves, test their snowboarding skill on the half pipe, or welcome spring showers with a walk in the rain and a colourful umbrella. All-new activities, like soccer, and big seasonal festivals and celebrations bring the spirit of each season to life. Your Sims can pucker up at the kissing booth at the spring festival, or see what Halloween surprises await in the haunted house. Dress for the weather with seasonal fashions from sun dresses to raincoats and snow gear. With new foods, dcor and weather effects, your Sims can enjoy the bounty and beauty of the ever-changing seasons and play with life like never before!

• Delight your Sims with new activities for every season: Whether building an intimate igloo, carving a scary Jack o’ lantern, taking a plunge off the diving board or setting off all-new fireworks, your Sim can always find new things to do throughout the year.
• Join the fun with seasonal festivals: Sims can get in a snowball fight at the annual winter festival, get their faces painted at the summer festival, whoop it up at the spring dance or bob for apples during the fall festival.
• Experience the joy and challenge of changing weather: New weather effects and Sim reactions capture the power and beauty of nature! Sims can get a tan, be struck by lightning or catch a cold!
• Bring the outdoors inside: Your Sim can now learn the recipe for pumpkin pie or style their home with new furniture and décor. There are a host of new items to ring in each season. Get a tanning booth in time for summer or ring in the holiday spirit with house lights and decorations.
• Dress for the weather: Outfit your Sim in new styles for the season, including snow gear, wetsuits, raincoats, umbrellas and new Halloween costumes!
• Welcome mysterious visitors: New weather patterns aren’t the only things appearing in the sky! Befriend an alien visitor and use their UFO to abduct a neighbor, invade a community lot or travel to the stars.
• Relax in style in the Limited Edition Ice Lounge: Let your Sims entertain in style with the elegant ice bar, bar stool and pub table. Items like the ice dining chair, dining, table, coffee table, sofa and loveseat can add distinctive style to any room in your Sims’ home. The ice lounge also includes architectural elements to add a subtle touch of style to your Sims’ buildings.
