Maple seeds (“helicopters”) in New York usually fall in spring to early summer , with many species dropping them in April through June ; some maples also release seeds in late summer or fall depending on the species. In warmer or milder years, you may notice a heavier drop earlier than usual.

What to expect in NY

  • Silver maple: often drops in April and May.
  • Norway maple: can shed an early crop in late May or mid-June , and then a more mature crop later.
  • Many other maples: release samaras in late spring or early summer , though timing varies by tree and weather.

Why timing changes

Weather matters a lot. Warm spells, mild winters, wind, rain, and tree stress can all change when the seeds show up and how many you see. Some years also produce a “mast year,” when maples make a much larger-than-normal crop of helicopters.

Practical rule

If you’re in New York, the simplest answer is: start watching in April, expect the main drop in May and June, and don’t be surprised if a few appear outside that window.

TL;DR: In NY, maple helicopters usually fall from April to June , with the heaviest drop often in May.
