Midsommar is the summer-iest horror movie I can think of, aside from the summer camp slasher types. They can be super fun. The recent Fear Street trilogy on Netflix had an entry like that, the second if I recall. Might rewatch it soonish.

For books, I'm very fond of The Elementals by Michael McDowell as a Summer read.

Can't think of any other seasons right now, it's too bloody hot.

The Lost Boys is pretty summery

We watch Halloween III: Season of the Witch every Halloween night, going on 20 years now. Similarly, we watch The Blair Witch Project on our anniversary each year.

Last year we decided to make Pontypool our Christmas horror movie---so here's to a new holiday tradition.

ps. Mrs. French's cat is missing.

My fiancé and I like to watch It (the new one) and the Shining close to Halloween time. Also the Halloween movies, for obvious reasons.

She likes to watch the Scream movies in the summer.

Beyond that, I don’t really look for an excuse to watch horror movies. 😅 I just watch them whenever.

Before it gets too hot in the summer, I love watching Dead & Buried and The Fog for its beachy-but-still-cold vibes.

I'm right there with you on Winter snowy movies. Obviously Black Christmas but The Thing and The Shining are musts.

I'm super into seasonal horror, and I'm constantly watching movies based on the time of year.

For summer I like slashers too, and really any 80s movies. It's also when I like to watch the dumb teen horror. Summer movies (80s horror): Prom night, Prom night 2, Death Spa, Return of the Living Dead, CHUD, Slumber Party Massacre, Slumber Party Massacre 2, Night of the Demons, Pledge Night, Hell Night, Slaughter High, Chopping Mall, Phantom of the Mall: Eric’s Revenge, Friday the 13th Franchise

Summer movies (other): Summer of ‘84, Truth or dare, Wish upon, The bye bye man, Slenderman

For autumn I like haunted house and Halloween movies, and more supernatural stuff that's actually creepy. Also the various rock horror movies they've watched on Best of the Worst. Autumn movies: Hell House LLC, Hellfest, Haunt, Extremity, Halloween Party, Terrifier 2, The Houses October Built, The Autopsy of Jane Doe, Hack’o’Lantern, Trick or Treat, Black Roses, Rocktober Blood, Scream, NoES and Paranormal Activity Franchises

And for winter I like, big surprise, winter and cold weather horror. Winter movies: Frankenstein Theory, Frozen, The Shining, Devil’s Pass (The Dyatlov Pass Incident), The Thing, We are Still Here, Wrong Turn 4, 30 Days of Night, The Blackcoat’s Daughter, Pontypool, Wind Chill, Paranormal Activity: Next of Kin, No Exit, The Curse of Aurore, The Last Winter

In spring I just watch whatever else is available.
