Best Time and Places to View the 2025 September Full Moon in the US

The 2025 September full moon promises to be one of the most spectacular celestial events of the year across the United States. As the Harvest Moon - the full moon closest to the autumnal equinox - this full moon viewing 2025 opportunity offers prime conditions for observation throughout North America. With minimal cloud cover predicted for most regions and the moon reaching perigee (its closest point to Earth), this September night sky 2025 event will showcase a brighter and larger-than-average lunar display.

Top Locations for September 2025 Full Moon Viewing

Prime Urban Observation Sites

For city dwellers seeking convenient best moon watching locations, several metropolitan areas offer surprisingly good conditions. According to the International Dark-Sky Association's 2024 Urban Night Sky Places report, these cities combine accessibility with relatively low light pollution:

• Denver, Colorado: The Mile High City's elevation reduces atmospheric interference, with the Denver Museum of Nature & Science hosting special viewing events (source: DMNS 2024 programming calendar)
• Portland, Oregon: Mount Tabor Park's volcanic cinderone provides elevated views above city lights, with 73% clear nights historically in September (NOAA climate data)
• Tucson, Arizona: Home to multiple professional observatories, the city maintains strict lighting ordinances that preserve dark skies
