Summer has begun, and TikTok is heating up with the season's hottest trends, with videos to add to your TikTok saved collections. Content creators, brands, or simply users who like to browse in search of inspiration… Everyone wants to be on top of what's catching the world's attention at the moment!

Here's a complete investigation into the viral TikTok trends that will define the summer of 2025. Also, take advantage of the tips to save the coolest videos on your TikTok saved collections and not miss any of them, even after the trends have passed.

1. ‘90s/‘00s Nostalgia

The wave of nostalgia for the 1990s and 2000s remains strong. Posts with the hashtag #Nostalgia have increased by almost 70% compared to the previous year.

The idea behind this trend is to recreate moments from childhood, showing discontinued snacks and memories of elementary school with pride and longing. This movement is making series like Sex and the City, The Vampire Diaries, Gossip Girl, Gilmore Girls, and the iconic British show Skins gain new fans in the new generation. Of course, Y2K style is also surfing this trend!

How to join in:

• Recreate scenes from your favorite 90s/00s series.

• Make a “What I wore in elementary school” or “Childhood snack taste test” series.

• Use #Nostalgia and #Y2K to stay on trend.

2. Going Green

Forget cucumbers, they're so 2024! Carrots are TikTok's new vegetarian star. Salads with grated carrots, carrot chips with salt and vinegar, and veggie bowls in all rainbow colors are trends in the gastronomy niche and for fitness users.

But the fitness niche has a favorite color: green! Pistachio, matcha, and pickles are dominating the trend. From pistachio chocolate bars to matcha-inspired nail art and pickle-infused drinks, creators are turning green foods into a status symbol for the summer.

Companies focused on healthy eating are hitting the nail on the head with this trend, using TikTok to create real connections and mouth-watering FOMO.

How to join in:

• Make recipe videos or healthy food reviews.

• Try painting your nails with the matcha or pistachio aesthetic and tag #GreenTok, #Pistachio, or #Matcha.

• For brands, highlight exclusive green menu items or products within the green aesthetic.

3. Hamptons Aesthetic: Old Money Goes Coastal

Some trends, naturally, are the face of summer, and the Hamptons aesthetic does just that. It's all about cozy comfort and quiet luxury here.

The videos using #Hamptons and #Cottagecore are like scenes from a Nancy Meyers movie: airy settings, pastel colors, sunset meals, and houses surrounded by white flowers. This aesthetic combines nostalgic coastal chic, Martha Stewart, and a quiet, effortless life. TikTokers are channeling the energy of “old money,” mixing Hamptons style with the moves of a coastal granny and quiet luxury.

How to join in:

• Share “Hamptons picnic” setups or “in my cottagecore life” daily vlogs.

• Try DIY flower arrangements, slow brunches, or chic summer outfits.

• Use #Hamptons, #CoastalGrandmother, or #Cottagecore.

4. Romantasy & Fandom Creativity

The #BookTok is on the rise (again) this summer. Romantasy — the irresistible mix of romance and fantasy — is everywhere, with series like Fourth Wing and ACOTAR spawning fan art exhibitions, AI images of characters and scenarios, and users cosplaying.

This trend is more than just popular reading. With big adaptations on the horizon (hello, the TikTok sensation The Seven Husbands Of Evelyn Hugo will be on Netflix!), creators are also turning book recommendations and reviews into lots of creative content.

How to join in:

• Review your favorite books, make “If you liked X book, try Y series” reels, or join the latest romantasy debate.

• Get creative creating book characters in AI art or fantasy edits.

• Don’t forget to tag #BookTok, #Romantasy, or #BookRecommendations.

5. Cowboys vs. Cotswolds

Country life fever is officially here! On the one hand, country life in the United States is thriving with content creators like @visit.yellowstone, with compelling content about the Yellowstone National Park region. On the other hand, the English countryside and the Cotswolds are booming, with hiking options, cozy village stays, and gardening gaining millions of views.

Whether it's wild outdoor adventures or peaceful routines in gardens, TikTokers are embracing the slower, cozier side of life. Creators like Martha Swales (@marfskitchengarden) share simple, sustainable gardening, inspiring us all, even if it's just to grow a pot of herbs on the windowsill.

How to join in:

• Share countryside walks, cowboy aesthetic travel vlogs, or your garden-to-table tips.

• Spotlight seasonal veggies and simple gardening hacks.

• Tag #CountryTok, #Cotswolds, #GardenTok for reach.

6. The Drama Comeback

If you like TV series, summer 2025 is your time. Crime dramas are going viral — as is the case with Netflix's #Adolescence, which has earned more than 75,000 views on TikTok.

South Korean dramas, a.k.a. K-dramas, aren't far behind! Series such as All of Us Are Dead and Alice in Borderland are also captivating a worldwide audience. We know that passionate K-pop fans are in on it!

How to join in:

• Do a K-drama watch vlog or create a “Crime drama I recommend.”

• Collab on duets or act out scenes.

• Use #KdramaTok, #CrimeDrama, and #BingeWorthy.

7. Women in Sport

Women's sports are having their big moment in the media right now. Olympic personalities such as @ilonaMaher, equestrian stars, and up-and-coming golf champions are engaging well on #WomenInSport. It's over 35,000 videos, and maybe you will want to add some to your TikTok saved collections.

How to join in:

• Share your sports highlights or raw reactions about women athletes.

• If you're a woman, share your training tips and favorite sports.

• Don't forget to tag #WomenInSport to be part of the movement.

8. Pop Girl Summer

It's official, the real masters of summer are the pop girls! They're at the forefront of viral releases, even cross-genre collaborations and covers. Rising stars such as Skye Newman (@skyenewman__) and Florence Road (@florence.road) are attracting attention on TikTok, while icons such as Charli XCX, Rachel Chinouriri, and Lizzy McAlpine remain on the rise.

What's hot? Mashups of genres — Amapian with DnB, R&B with indie — are creating the soundtrack for summer 2025. Nostalgia is also here, with tracks by Imogen Heap, Jessie J, and “Pretty Little Baby” by Connie Francis (with over 20 million videos!).

How to join in:

• Hop on trending dance or lip-sync challenges.

• Review or remix your fave female-led summer tracks.

• Tag #PopGirlSummer, #ViralSongs, and #GirlPower.
