Hey, Simmers!
The Sims 4™ Seasons Expansion Pack* is coming soon, and we want to give you an idea of what to expect in each season. We talked a bit about spring and summer, but now it's time to spark the fireplace, brew some tea, and watch the leaves change on neighborhood trees. Let's get to fall, winter, pumpkin spice, and everything nice, shall we?
Set the Date
To kick things off, one of the most significant features of this expansion pack is the calendar. So, let's talk about it! The calendar includes all upcoming holidays. Each one includes traditions to complete that make progress toward your Sim having an awesome time celebrating. Plus, predicted weather conditions can help Sims plan ahead. You'll also see the schedule of your Sim's household while checking out the calendar, including when they have to go to work. And to make even more planning possible, Sims' birthdays will be featured on the calendar. Pop open some nectar (for New Year's, that is) because all this and more will be in one place. Now that's an organized Sims game.
Simmers, Start Your Ovens
When chilly weather rolls around, so do holidays! Harvestfest is in the fall, when Sims gather their closest friends and family for the grand meal. Sims can decorate their home for this special day, throw a turkey in the oven, and cook up some delectable goodies for the whole brood. Looking for an extra guest to join the gathering? You may find yourself encountering a certain straw-filled friend made especially for your garden.
When winter blows into town, so does Winterfest! Customize homes with a holiday pack and decoration box, give gifts, sip hot cocoa, and so much more. You won't want to miss a special visit from Father Winter. He'll be sure to brighten any Sim's holiday spirit.

Baby, It's Cold Outside
It wouldn't be fall and winter without a flurry of chillier activities. So, for the first time in The Sims 4, we're introducing ice skating. Tricks, spins, and awkward falls await your Sims when you place the skating rink. Plus, Sims can arm themselves with hats and gloves, then head outside to make a snowpal and snow angels.

Speaking of seasonal happenings, are your Sims ready to fall in love? Adventurous Sims can ahem express their feelings for each other in a leaf pile! Yeah, you'll probably want to leaf them alone for a while. (Sorry-not-sorry for the puns.)
As you may expect, the not-so-fun parts of winter blow in, too. For one thing, it's freeeezing! And without the proper outfit, your Sims will shiver and shake in their boots. Make sure to bundle up before heading outdoors for longer periods of time. If you don't, your Sims will be so blue. Literally. The colder they get, the higher the risk of - you guessed it - death. Womp womp.

can't say I'm very impressed with this significant feature. Obviously just my opinion but I don't see the hype around it.
I guess this is the new seasonal lot maker

I like her dress too. It looks so warm and fluffy ^^
Agreed. I quite like the dress itself as well, though I'd probably prefer it in a different color...
The words "I told you so" spring to mind.
I think you've worded my feeling about it better than I have. It feels like an update not a major feature for an expansion pack.

I need nectar making option in ts4 so badly...
It would be cool if they added that. Do we already have nectar in sims 4?

Snow shoveling, merry christmas, hope all your prayers have been answered.
snow shoveling isnt enough for you?
In all seriousness though, father winter seems new, he was in sims 2 but making your own holidays seems amazing. Tree decorating as well!
As long as returning activities have some twists to them that would be enough for me probably...
I'm so excited about gift giving. Now I can actually give sims presents instead of sitting out CC gift boxes and just pretending they opened them lol.
Anyone know if sims can ice skate on any frozen water or is it only available on the designated ice rink? That would be disappointing if we can't just ice skate on a frozen pond or lake.
Don't think we know that yet but I wouldn't get my hopes up. I think it would be really cool but as they haven't showed anything yet I don't think it'll be.

Boy I love those Autumn Decorations. Now I know why we didn't get them in a patch. They was saving those for Seasons.
