September 2027 is a month of health and heritage campaigns. World Alzheimer's Month runs all month, World Suicide Prevention Day falls on Friday 10 September, and Hispanic Heritage Month opens in the US on 15 September. One thing is different this year: Rosh Hashanah and Yom Kippur both fall in October, so September carries no Jewish High Holy Days.
Sport is unusually heavy. The World Athletics Championships are in Beijing from 10 to 19 September, the Ryder Cup comes to Adare Manor in Ireland a century after the first match, and the FIBA Basketball World Cup closes in Doha on 12 September. Add three Formula One weekends, England's white-ball series against New Zealand and the first British & Irish Lions Women's tour, and there's a lot to plan around. Here's PepTalk's guide to the cultural highlights of September 2027.
September 2027 – Month-long Observances
- World Alzheimer's Month | September 2027 Run by Alzheimer's Disease International to challenge the stigma around dementia, with World Alzheimer's Day on 21 September. The 2027 theme had not been announced at the time of writing. Author, broadcaster and dementia campaigner Sally Magnusson MBE is a strong fit for organisations marking the month.
- Hispanic Heritage Month (US) | 15 September – 15 October 2027 Celebrates the history, culture and contributions of Hispanic and Latino Americans, opening mid-month to coincide with the independence days of several Latin American countries. See our Hispanic Heritage Month speakers for programming ideas, or browse PepTalk's Hispanic and Latinx speakers.

A useful pair for a low-cost sustainability push, and PepTalk's sustainability speakers can turn either into a session.
- National Inclusion Week (UK) | September 2027 (dates to be confirmed) Inclusive Employers has said the week returns in September 2027 but had not published dates or a theme at the time of writing.

Book a speaker for September's awareness days

Devon, a mental health campaigner, author and broadcaster, speaks on building supportive workplace cultures, and Mulenda Record, author of Speak Up, brings a Gen Z perspective on wellbeing and leadership.

Paula Radcliffe MBE is a natural fit for a September built around the World Athletics Championships, the Great North Run and the Berlin Marathon. A world champion marathon runner and Olympian, she speaks on endurance, resilience and performing when it counts.
