there's plenty, but it also depends what you're looking for, spells utilizing the seasons energy, spells with seasonal ingredients, or spells that work better in this season [keeping in mind all spells work all year round]
as we enter the darker half of the year in the Northern Hemisphere we focus inward at this time and do spells/rituals more for self improvement. [shadow work is very popular around this time] a simple autumn one i heard about last year is pick up an acorn in the fall and carry it with you as a protection charm, in the spring leave the acorn somewhere off property in the new spring grass, this will bring all the negative energy the seed has collected throughout the winter with it. [there was also a similar one where you held the acorn and charged it with your hopes for the coming year] granted, if you don't live somewhere with a large supply of oak [i do, not to give my town away but it's basically THE place to go if you want oak trees]
you can also use the energy surrounding the pagan holidays of this time to aid your journey. Mabon is a time of balance and thanks, so the time leading up to and just past Mabon can be a great time to give thanks, balance thing [budget, chakras] cleansing. you could also start preparing for future goals. Samhain is a time of divination, but also a lot of love spells around this time. it's also Pagan new year, so wishes for the months ahead and putting plans into action, would be great at this time. [i know a number of pagans who begin their new years resolutions on Samhain, so they can be set for the calendars new years] you also have Yule which is a time of rebirth and celebration [and i know some Norse pagans also celebrate 12 days each for a specific deity. if you follow a different path, look into what historically was celebrated at this time. not sure how many practice Saturnalia lol] get together with loved ones, give gifts, cast spells for new beginnings [luck, wealth, job, love] as well as strength spells to go with the strength of the sun [though i feel they're best done on Midsummer]
in the winter you can use winter plants like holly, you can also look into freezer spells and snow spells [not 'let it snow' but using actual snow in your spell] if you want me to mail you some spells from my Llewellyn calendar i can [each month has a write-up and a little spell/ritual from different authors. October was written by Elizabeth Barrette and the spell is 'embracing your peak of perfection' by connecting with the Horned God and tapping into his energy] you might also like the Llewellyn essentials collection on the sabbats. it's 8 books [nice size, not too big] ghost written by Llewellyn authors detailing each of the 8 sabbats including rituals, spells, activities, history, and lore. i also recently got Deborah Blakes newest book and it gives you something witchy to do every single day. sometimes it's spells, other times it's information. [today was black cats. nothing very informative, just 'black cats have superstition around them, some countries consider them good luck, next time you wish to adopt a cat, try finding a black one' a few days ago she wrote a courage spells that i really liked so it's a grab-bag]
