Don’t miss out on Mother’s Day night to look forward to watching the Perseids meteor shower with the naked eye from the night of 12 Aug until early morning 13 Aug. This year is favorable with no moonlight interference, and the peak average rate is expected to be about 100 meteors per hour.
On 11 August 2026, Mr. Supharuek Karuhanon, Assistant Director of the National Astronomical Research Institute of Thailand (NARIT), announced that from the night of 12 August 2026 until the early morning of 13 August 2026, the Perseids meteor shower will occur, commonly called the "Mother’s Day meteor shower." The radiant point is located in the Perseus constellation, rising from the northeastern horizon around 23:00 on 12 August 2026. Viewing can continue until the early morning of 13 August 2026, with an expected peak rate of about 100 meteors per hour.
This year, there will be no moonlight interference during the event, making it ideal for observation. It is recommended to watch from areas away from cities or places without light pollution. The best way to observe the meteor shower is to lie back and watch with the naked eye toward the direction of the meteors’ radiant. If weather conditions are clear and rain-free, the beautiful Perseids meteor shower can be seen throughout the country.
However, Thailand is currently in the rainy season with heavy rains in many areas. If you miss this event, other meteor showers occur regularly every year for future viewing opportunities.
The Perseids meteor shower is the second brightest after the Leonids, visible annually from 17 July to 24 August, typically peaking on 12-13 August. Its colorful meteors originate from dust left by the Swift-Tuttle comet (109P/Swift-Tuttle). When Earth passes through this dust, particles enter the atmosphere and burn up, producing bright streaks of light. This natural phenomenon has no impact on Earth.
