Boom is looking at a temperate start for the 2026 edition, with mild sun and highs of 26°C expected for the opening weekend.
The first weekend of Tomorrowland kicks off tomorrow under favorable conditions. Friday stays warm at 26°C with minimal light rain, transitioning into a drier, breezy Saturday. As Calvin Harris and Alesso close out Sunday, expect clear skies and a steady 21°C.
Weekend two projections currently suggest a more intense heat spike. Early data from the BBC and The Weather Channel point toward highs of 29°C. While light drizzle remains a possibility, the consensus suggests a mostly dry run for the later dates.
On-site action starts Friday at 14:00 CEST. For those not in Belgium, the 2026 streaming program covers the Mainstage and Freedom Stage throughout both weekends. Set times are confirmed and live.
