When is the Harvest Moon? From London to Tokyo to New York, key timings for the full Moon this weekend

The Harvest Moon rises this weekend! Here we'll give you key timings for the rise of the Harvest Moon across the world's major cities, plus some tips on how to make the most of it.

On Friday, Saturday and Sunday night, 25–27 September 2026, the full Moon will rise in the sky shortly after sunset.

This is the Harvest Moon for the year because it's the closest full Moon to the September equinox.

What that means is that the rise times for the Moon are roughly the same time over the coming nights, which traditionally meant a reliable source of moonlight over consecutive evenings for gathering the harvest.
