The 2025 Equinox: Marking Seasonal Shifts and Its Impact on Climate
The equinox is an astronomical phenomenon that occurs twice a year in March and September, marking the beginning of spring and autumn in the Northern and Southern Hemispheres, respectively. The equinox will take place on Thursday, March 20, 2025, at 16.01 WIB.
Understanding the Equinox
The equinox happens when the sun is directly above the equator, making the lengths of day and night almost equal throughout the world—approximately 12 hours each.
According to the Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG), the equinox occurs when the sun is positioned directly above the celestial equator, aligning the Earth’s equator with the plane of the earth’s orbit around the sun.
The Impact of the Equinox
During the equinox, the Earth and sun are closest to each other. This proximity results in maximum solar irradiation around the equatorial region, increasing air temperatures. However, this effect is not as drastic as a heatwave, reassuring that there is no need for alarm regarding extreme temperature fluctuations.
The equinox is a recurring event rather than an event leading to extreme temperature changes. Typically, during the equinox, which occurs in March and September, there might be a noticeable but manageable increase in temperatures.

Seasonal Shifts
The March equinox marks the onset of spring in the northern hemisphere and autumn in the southern hemisphere.
Overtop the Equator
During the equinox, the sun is directly above the equator, leading to near-equal day and night durations—approximately 12 hours each. The impact of the equinox makes itself known via enhanced solar radiation in the equatorial region, elevating temperatures, albeit without trigger the heat waves.
Key Dates and Timing
| Equinox | Typical Date Range | 2025 Date and Time |
|---|---|---|
| March Equinox | March 19-21 | Thursday, March 20, 2025, at 16.01 WIB |
What to Expect from the March 2025 Equinox
The March equinox tends to happen within a few days, typically on March 19, 20, or 21 each year. During equinox, the duration of day and night is almost the same worldwide, with about 12 hours for each.
Did you know? The August Full Moon is also known as the Sturgeon Moon, once used to describe the time of year when sturgeon were most readily caught.
Impact of the Equinox:
Despite the increase in solar irradiation around the equator, the rise in air temperatures does not dramatically change weather conditions. People can be assured that this phenomenon is nowhere close to the intensity of a heatwave.
While the equinox is more of an alignment for seasonal changes, and a more serene experience that does not greatly affect temperature extremes, it does prompt weather watchers to keep an eye on changing temperatures.
Authoritative Voices on the Equinox
BMKG has provided reassurance regarding the impacts of equinox. People can be at ease, knowing that the effect of equinox is not an adverse phenomenon. Equinox is simply part of our Earth-Sun distance effects day and climate cycles – not something to worry about.
Equinox Facts
-
Aligned Harmony: The equinox occurs when the Earth is tilted such that the Sun is directly over the equator.
-
Global Length of Daylight: The length of day and night during the equinox is roughly equal.
- Seasonal Shifts: The March equinox signifies the start of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
FAQs
Q: What is the difference between the March and September equinox?
A: The March equinox marks the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere, while the September equinox marks the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
Q: Does the equinox cause drastic temperature changes?
A: No, the equinox does not cause extreme temperature changes. It briefly increases solar irradiation in the equatorial region but does not result in significant temperature fluctuations.
Q: Why is it called an equinox?
A: The term "equinox" comes from the Latin words "aequus" (equal) and "nox" (night), referring to the nearly equal lengths of day and night during this phenomenon.
Pro Tips:
Keep an eye on local weather updates during the equinox, as slight fluctuations may occur. Ensure you stay hydrated and wear sun protection during peak daylight hours, even though the overall impact is mild.
