The monsoon has already arrived in Northeast India in 2026 —by early to late June, IMD-linked reports said it had reached the region and that heavy rain continued through at least June 25.

Quick scoop

  • A June 4 report said conditions were favorable for the monsoon to reach Northeast India in 2–3 days , with the normal onset date there around June 5.
  • By June 21–22, reports said the southwest monsoon had arrived at full force in the Northeast, bringing intense rain and landslide warnings.
  • On June 27, IMD material still pointed to heavy to very heavy rain in Northeast India and sub-Himalayan West Bengal and Sikkim this week.

What that means

If you mean the usual monsoon onset , Northeast India typically gets it in early June , and in 2026 it appears to have set in around that window.

If you mean when the rains ease , that varies by state and local weather systems, so the monsoon season can stay active well beyond onset.

One-line answer

Northeast India’s monsoon for 2026 started in early June, roughly around June 5–7, and remained very active through late June.
