As the temperature rises, so too does your chance of falling in love -- or so Hollywood would have us believe.
Regardless of whether that's actually true or not, you can't deny the appeal of the summer romance -- particularly when it's played out by celebrities on screen.
Sure, some end tragically (do not think about 'My Girl'. Do not think about 'My Girl'.) but most never fail to leave an impression -- or at least, a really good kissing scene.
From Sanny and Danny to Noah and Allie -- here are some of the top summer love affairs of the big screen.
WARNING: Smooches ahead.
Danny and Sandy, 'Grease' (1978)
Ahhh, who could forget the summer lovin' (havin' a blast!) between smooth-talking Danny Zuko and sweet-as-pie Aussie Sandy Olsson.
There's nothing quite as sweet as young holiday love blossoming between two teenagers who, after saying their respective goodbyes, then face the unlikely surprise of starting the new year at the same US high school.
While your vacay romance might not want to make you break into song and dance with a random chick in a poodle skirt, it could make you consider taking up track or, in Sandy's case, leather pants and smoking (the latter definitely not recommended.)
At at the very least, if it doesn't work out, you know you each have your respective squads to fall back on. T-Birds and Pink Ladies #4lyf.
Noah and Allie, 'The Notebook' (2004)
It doesn't get much more romantic than 'The Notebook'. It's a story we've heard a hundred times before -- when poor-as-dirt Noah Calhoun meets the well-to-do Allie Hamilton at a fairground, he's so smitten he climbs a ferris wheel in order to get her to date him.
Subsequently, they dance in the street, have steamy make-out sessions in the car and say things like "if you're a bird, I'm a bird" before eventually being torn apart when the summer inevitably ends.
Fast forward a couple of years and Allie is engaged to someone else, only to find out Noah is totally not over it and has built her a house. She goes to visit him because she's freaked out she doesn't paint anymore, then she and Noah check out some geese before pashing in the rain.
In the end they live happily ever after and die in bed at the same time. Should I have said something about a spoiler alert? It was made in 2004. If you don't know the ending by now, you can't be helped.
Baby and Johnny, 'Dirty Dancing' (1987)
NOBODY PUTS BABY IN A CORNER.
OK, so the dancing in this movie makes Danny and Sandy's innocent bopping looks like child's play, but because now we're in the 80's that's totally allowed.
Frances "Baby" Houseman meets Johnny Castle while her family is vacationing at a fancy resort where Johnny works. Because Johnny is a) played by Patrick Swayze and b) has rad dance skillz it doesn't take long for Baby to develop a pretty serious crush on him. She's only human, y'all.
Then, when Johnny's usual dance partner Penny falls pregnant to a womanising waiter, she decides to have a termination which ultimately leaves her in terrible pain -- leaving Baby to step in as Johnny's new partner. OK, when you write it down it's admittedly not the most ideal situation in which to start a romance but that's just how it worked out, k?
Cue lots of steamy rehearsal scenes -- complete with one in a lake -- and love happens.
Plus at the end Johnny gives a really cute speech about how "Frances" has changed his life and they dance to "I've Had The Time Of My Life" and Baby nails that famous move which, this reporter knows from experience, should not be attempted while intoxicated on New Year's Eve.
Thomas J. and Vada, 'My Girl' (1991)
So we said we wouldn't go here but how could we not? Thomas J. and Vada were the best. Look at Thomas J.'s cute little face when Vada kisses him! Cuuuuuuuute.
'My Girl' follows these two besties as they while away the hot summer riding their bikes, sitting in a big tree and occasionally going fishing. It is innocent love at its best and there is nothing more tragic than when Thomas J. goes back to find Vada's beloved mood ring in the forest, only to be stung by heaps of bees -- which he's allergic to -- ultimately killing him.
Ugh, is it hot in this office? Why am I sweating from my eyes?
'My Girl 2' tried to pair Vada up with some other dude but we knew in our hearts he didn't have a patch on Thomas J, his adorable glasses and love of cold glasses of milk. Thomas J. -- the ultimate bf.
Ennis and Jack, 'Brokeback Mountain' (2005)
While all this eye-sweating is going on, it's only appropriate to visit 'Brokeback Mountain' -- one of the most tragic summer romances in movie history.
Ennis and Jack meet when they are sent to work on 'Brokeback Mountain' to herd sheep over the summer. It is here they start a romantic relationship -- which Ennis initially fights -- that will last the rest of their lives.
With Ennis refusing to live a life together in the open, both go onto marry other woman and have families, though they keep their relationship alive by stealing away on romantic "fishing" trips. Jack continues to ask Ennis to leave his wife and be with him, but Ennis won't abandon his family.
When Ennis receives news of Jack's death years later, he goes to visit Jack's family, and finds an old shirt of his hidden in his lover's closet. It is a shirt he thought he had lost on that initial 'Brokeback Mountain' summer, all those years ago, which Jack had secretly kept along with one of his.
Ennis takes both shirts and keeps them in his own closet with a postcard of Brokeback Mountain pinned above them. Sob.
Vicky and Cristina and Juan and Maria, 'Vicky Cristina Barcelona'(2008)
BONUS! Two gifs because there is a LOT going on in this movie.
Here's the lowdown.
Vicky and Cristina go to Barcelona (props to Woody Allen for a distilled, to-the-point movie title). Here they meet mega babe artist Juan, whom both girls totally get the hots for and end up having intimate relations with.
Cristina is ultimately more suited to Juan so they move in together while she dabbles with photography and drinks lots of wine.
Then Juan's equal parts hot/crazy ex-wife Maria enters the picture. She and Juan end up rekindling their relationship, which Cristina tries to be cool about because #bohemianliving, and then Maria and Cristina get it on in a darkroom, which Juan was probably pretty chuffed about.
In all seriousness though, the film stars Javier Bardem, Penelope Cruz and Scarlett Johansson and frankly, they can do whatever they want and it will always make sexy perfect sense.
Jesse and Céline, 'Before Sunrise' (1995)
DISCLAIMER: if you meet a sexy stranger on a train and he asks you to get off with him in Vienna -- it might not turn out in the way you expected.
In the case of Jesse and Céline, however, what ensues is lots of walking, talking, kissing and general love-blossoming.
They spend a magical day and night together before both must part ways the next morning -- with the pair deciding not to exchange contact information, but to meet at the same station in six months time.
Since it sparked two sequels, pretty sure this was more than a one-day fling.
Romeo and Juliet, 'Romeo + Juliet' (1996)
Ah, the original summer romance -- Romeo and Juliet. OK, while admittedly their romance lasted five days and heaps of people died, it's still one of the greatest love stories of all time.
We don't think this really needs explaining, unless you've been living under a rock since 1616, but basically -- Romeo and Juliet aren't allowed to fall in love because their families hate each other.
They do anyway, get married in secret and then form a very elaborate plan to get Juliet out of marrying this other dude, Paris.
In short it doesn't really work out for anyone.
However, in terms of a relationship that played out entirely in under a week -- it's a pretty memorable one.
