Here are some of the biggest trends:

Top TikTok Trends in September 2025

  1. #AutumnCozyChallenge
    As fall arrives in many places, this trend encourages users to show their favorite autumn routines—warm drinks, comfy clothes, cozy decor, reading nooks, etc. Videos are often styled with soft lighting, leaves, pumpkins, blankets. Brands are using it to showcase autumn products or even self-care routines. Pepper Agency+1

  2. #BackToRoutine
    The return to school or work after vacation/informal summer routines brings this trend: productivity, morning rituals, work-from-home setups, schedules, planners, organization. It has a motivational feel with users showing how they re-establish patterns. Pepper Agency+1

  3. #SustainableSeptember
    Environmentally conscious content is trending. Creators are sharing eco hacks, zero-waste swaps, sustainable fashion, upcycling, small lifestyle changes that reduce plastic, carbon footprint, etc. Brands are engaging by highlighting sustainability credentials, promoting ethical sourcing, etc. Pepper Agency+1

  4. Viral Audio & Dance Challenges
    As usual, certain sounds are being used heavily. Some of the sounds/dances in rotation include:
    ‒ “Fastlane” by Chubz — used for hype, energy, speed, progress content. SocialPilot+1
    ‒ “Estouracao Automotiva” (Brazilian funk style) — used for car edits, loud visuals, dance. SocialPilot+1
    ‒ “Upside Down” by Jack Johnson — for nostalgic moods, everyday joyful moments. SocialPilot+1
    ‒ “I’m Not Them” — used by creators to assert individuality, highlight transformations, “not following norms” themes. SocialPilot+1

  5. “Talent is a Pursued Interest” Growth/Glow-Up Videos
    This is a motivational/trend audio piece (sometimes using Bob Ross references) in which creators show progress over time: painting, singing, fitness, personal development. The idea is that “talent” is not innate but built through practice. People share early/unfinished versions then show recent improvements. Ramd

  6. Seasonal & Nostalgia Vibes
    Many creators are leaning into autumnal aesthetics, nostalgic references (90s/2000s), soft filters, nostalgic audio clips or tunes. Pumpkin-spice everything, cozy sweaters, Halloween prep, warm lighting, fall color palettes. Accio+2NapoleonCat+2

  7. “I’m bored, tell me about … ” / Storytime Trends
    Story-telling is back. Prompts like “I’m bored, tell me about a time …” or “POV: the moment I realized …” are popular. These allow users to share personal, entertaining, emotional, or funny stories. NapoleonCat+1

  8. Hashtag Strategies & Product / Lifestyle Content
    Trending hashtags this month include #fallvibes, #pumpkinspice, #fallaesthetic, #skincareroutine #fallfashion etc. Also content showing cozy product promotion, lifestyle tips, and shorter “how-to” or “hack” style content with authenticity. Accio+1

Why These Trends Are Happening

  • Seasonal shift: Autumn in many parts of the world brings changes in mood, activities, and visuals. People want cozy and comforting content.

  • Back to routine: End of summer/school/work cycles prompt reflection and re-organization.

  • Heightened awareness: Environmental topics and sustainability are more mainstream left.

  • Desire for authenticity: Trends like growth, stories, behind-the scenes reflect users’ craving for realness in contrast to polished perfection.

  • Nostalgia and escapism: When life feels fast or uncertain, fuels like nostalgic songs, familiar aesthetics, cozy visuals help anchor people.

Examples of How Creators / Brands Are Using These Trends

  • A creator documents their autumn transition: switching closet pieces, lighting candles, pumpkin décor, playlist, etc., using #AutumnCozy and a trending audio.

  • A fitness influencer showing “back to my routine” after summer: early morning workout, prepping meals, setting new goals.

  • Brands launching eco-friendly packaging or sustainable product lines for #SustainableSeptember, and inviting users to share their swaps (e.g. cloth bags, refillable bottles).

  • Using “Talent is a Pursued Interest” audio to show progression in painting, makeup, public speaking. These often do well because people love transformation.

  • Storytime prompts like “I’m bored, tell me about your most embarrassing school moment” etc., or big revelations with POV format.

Tips If You Want to Ride These Trends

If you’re a creator or brand and want to make content that resonates in September 2025, here are some tips:

  1. Be timely: Use autumn visuals, fall decor, back-to-school/work routine, seasonal foods. If your content feels timely, it tends to perform better.

  2. Use trending sounds early: If you spot a song gaining traction (Fastlane, Automotiva, etc.), use it before it saturates. Algorithms often reward early adoption.

  3. Mix authenticity + polish: Storytelling, behind scenes, progress/growth work well — people appreciate imperfect content. But the visual style still matters (good lighting, clear audio).

  4. Hashtags: seasonal + niche: Use general tags like #fallaesthetic, plus niche tags related to your content (fashion, food, crafts) to reach your audience.

  5. Interactive formats: Polls, POVs, story prompts, challenges where audience can respond or duet. These get engagement.

  6. Sustainability or purpose-driven content: Even small efforts (like packaging, waste, eco choices) can stand out, especially when tied to trends like #SustainableSeptember.

What to Watch Out For

  • Trend saturation: Some sounds or challenges become overused fast, which makes new content less surprising.

  • Cultural / regional relevance: Autumn vibes or “fall” aesthetic may work better in northern hemisphere, less in regions with different seasons. Adapt visuals accordingly.

  • Authenticity fatigue: Audiences are wary of overly curated content that feels like marketing dressed up. Real stories often perform better.

  • Platform algorithm changes: TikTok may tweak what’s prioritized. What works one week might not the next.

  • Overuse of sound rights / licensing: Using copyrighted music carefully to avoid takedowns or muted videos.

What’s Likely Coming Up

Based on where things are now, some trends to keep an eye out for in the near future (later fall / early winter):

  • More holiday prep content (Halloween & then early winter holidays) but perhaps earlier than ever.

  • Even more nostalgia: retro clothing, throwbacks to early internet / early social media aesthetics.

  • AI tools / filters: More advanced visual effects, AI image generation, editing magic to augment content.

  • Wellness & mental health content: rituals, routines, self-care, dealing with burnout.

  • Cross-platform mashups: Creators who post snippets that perform well on TikTok and get reused on Instagram, YT Shorts, etc.

Final Thoughts

September 2025 feels like a turning point: people are looking inward, slowing down a bit, embracing comfort, identity, and purpose — while still enjoying the energy of viral sounds and creativity. The best TikTok content this month tends to blend visual/narrative warmth (coziness, authenticity, transformation) with sound/music that triggers nostalgia or excitement.
