Does the Total Solar Eclipse Affect the Tides?

Does the Total Solar Eclipse Affect the Tides? While the moon’s gravity causes the tides, a solar eclipse does not directly impact them. However, an eclipse offers a glimpse into sea level rise’s effects. Learn how to safely view this celestial wonder.

    The Moon’s Gravity and the Tides

    The tides on Earth are primarily caused by the gravitational pull of the moon. As the moon orbits Earth, its gravity pulls on Earth’s oceans, causing the water to bulge out in the direction of the moon. This bulge moves around Earth as the moon orbits, creating the daily tidal cycles. According to research from MIT, during a total solar eclipse, the moon blocks the sun, but its gravitational pull on Earth remains the same. So while the solar eclipse may briefly affect solar energy and weather, it does not directly impact the tides.

    A Preview of Sea Level Rise

    However, MIT research found that the solar eclipse may provide a preview of the effects of sea level rise. As the researchers explain,” the solar eclipse causes a sudden drop in solar radiation, which leads to a drop in air and ocean temperatures, as well as a decrease in wind speeds.” These effects are similar to what we may experience with long-term sea level rise and warming. The researchers were able to study the ocean’s response to these changes during the 2017 total solar eclipse.

    Be Safe and Enjoy this Celestial Event!

    While the tides themselves are not impacted, a total solar eclipse is still an incredible sight. To view the eclipse safely, you’ll want to obtain solar eclipse glasses that meet the ISO 12312-2 international standard for such eyewear. You can find high-quality, affordable solar eclipse glasses at the Eclipse Store. Enjoy this rare celestial event, but be sure to take proper precautions to avoid eye damage.


    The total solar eclipse does not directly impact the tides, as the moon’s gravitational pull remains the same. However, the solar eclipse may provide a preview of how sea levels could rise and affect the oceans in the future.
