Overview
- Peak illumination is expected around 11:48 p.m. ET on Monday in the U.S. and at 05:47 a.m. on Tuesday in Spain, with bright views both nights without a telescope.
- The full moon’s proximity to Earth will make it appear roughly 7% larger and about 16% brighter than an average full moon, with the best views from dark locations with a clear horizon.
- Stronger tides are forecast in coastal regions, with MeteoGalicia warning of pronounced ranges this week, including up to a 3.8‑meter difference in parts of Galicia.
- Moonlight will wash out many faint meteors during the Draconids peak on Oct. 8–9, reducing visibility for that shower.
- This is the first of three consecutive supermoons in 2025, followed by the Beaver Moon on Nov. 5 and the Cold Moon on Dec. 4.
