World Swim Hat Day 2026 – 7th Annual Celebration

Sport & outdoors · The kids’ pool, Marieviksbadet, on the waterfront promenade in Marievik (Liljeholmskajen)

Put something fun on your head and join the fun! Born in Stockholm, World Swim Hat Day has since spread around the world. This playful annual tradition celebrates creativity, collective joy, and getting weird together. 13:00 – Gathering & warm-up. 14:00 – Group plunge (wearing hats!). Take Festival Bus 5 to Marievik – almost as if SL created it just for the occasion! Not in Stockholm? Swim local and tag #worldswimhatday and @worldswimhatday.
