The Perseid meteor shower is expected to peak near mid-August this year, but unfortunately for Northern Hemisphere observers, the moon’s presence will make it difficult to view the best display. The moon will be at its fullest on Aug. 9 and a waning gibbous phase just a few nights later, seriously hampering observation of the peak.
The moon’s bright light will flood the sky through most of the key night, making it challenging to spot meteors. In fact, a waning gibbous is one of the worst moon phases for meteor watching. The Perseids will be visible from 11 p.m. or midnight until dawn, but with the moon in the way, observers can expect fewer than half of what they would see during a clear night.
However, if you’re willing to forego quantity for quality, some bright and fast Perseid meteors can still be seen through the moonlight. Some Perseids are also known to leave spectacular trains that can burn right through a moonlit sky.
Next year’s peak will coincide with a new moon and a solar eclipse, making skies dark and meteors plentiful. In 2026, viewers can expect a much better viewing experience. For now, observers can still catch a glimpse of the celestial streakers courtesy of one of the flashiest meteor showers of the year.
