UK summer 2026 on track to break 2025 heat record

Met Office data due Tuesday is expected to confirm summer 2026 as the UK's hottest on record, surpassing the 2025 benchmark after a season of persistent heat. The confirmation would mark a second consecutive record-breaking summer, underscoring an accelerating warming trend in the UK. This is a climate data point with implications for policy and infrastructure planning, though not an immediate market shock.
