August is proving to be a month rich in astronomical phenomena. Following the solar eclipse—which was partial across most of the country and total at Montesinho Park in the district of Bragança—one of the year’s most anticipated meteor showers reached its peak: thePerseids . However, for those who love stargazing, the calendar doesn’t stop there, as the Sturgeon Full Moon is just around the corner .
According to the specialized website StarWalk, the most spectacular view with the naked eye—or the ideal moment to capture a landscape photograph—occurs “near the moonrise at your location, at dusk closest to the exact moment of the full moon.” The same source notes that observers in Lisbon should look up at the sky at dusk on August 27, around 7:58 p.m., although the exact full moon will occur at 5:18 a.m. on August 28 in mainland Portugal.
It’s also worth noting that this Full Moon coincides with a deep partial lunar eclipse, which reaches its peak during the afternoon of August 28. In Lisbon, however, the peak occurs before moonrise, so viewing will depend on local time and weather conditions.
Where does the name of this full moon come from?

Like other full moons, theSturgeon Moon owes its name to the Native American peoples who lived around the Great Lakes.
For many locals, this was the prime time of year for fishing for sturgeon—a large freshwater fish, hence the origin of this name.
Viewpoints for observing the phenomenon
So you don’t miss a thing (and can snap that ‘perfect’ photo), we’ve rounded up some of our favorite spots in Lisbon for stargazing. Now, all you need to do is cross your fingers and hope the clouds don’t get in the way of your view of the Sturgeon Full Moon.
Here are some of the places we recommend:
- Senhora do Monte Viewpoint —there’s no getting around it, this is one of those classics that always deserves a mention. Open 24 hours a day, it offers you a view of São Jorge Castle, the historic center, and the Tagus River illuminated by moonlight.
- Penha da Graça Viewpoint —offers a particularly good view of the eastern part of the capital (Chelas, Marvila, and Olivais) and the river. Be sure to check the site’s accessibility before heading out.
- Alto da Serafina Viewpoint — if you want to escape Lisbon’s light pollution, the Monsanto Forest Park is undoubtedly a place to consider
- Graça Lookout (Sophia de Mello Breyner Andresen) —the panoramic view of São Jorge Castle and the Tagus River creates the perfect silhouette to frame the enormous Sturgeon Full Moon in photographs
- São Pedro de Alcântara Viewpoint —the prime vantage point for São Jorge Castle and the Alfama neighborhood, among other spots.
When is the next full moon?
Come September, you’ll be able to observe the Harvest Full Moon on the night of the 26th.
