About Onda
Onda is a municipality in the province of Castellón, in the Valencian Community, with around 24,850 inhabitants. Located at 192 metres altitude in the interior of Castellón, the town has roots dating back to the third century before Christ. Its position in the foothills of the Iberian System, between the coastal plain and the pre-littoral region, makes it a well-connected hub between the Mediterranean coast and the provincial capital.
For this eclipse
On 12 August 2026, Onda will lie within the path of totality of the solar eclipse. The moment of maximum will occur at 20:31, local time, when the Sun will be just 4.6° above the horizon in the west-northwest direction (azimuth 286°). With such a low angle, any natural obstacle or building to the west could intercept the moment of totality. The calculated verdict is marginal: finding a western horizon completely clear is essential to witness totality.
The weather in August
August is the brightest month of the year in Onda according to AEMET records for the period 1991–2020. The average temperature is around 26 °C, with typical highs above 30 °C and night-time lows around 21 °C. The sky is clear on 72 % of days, and the month accumulates more than 300 hours of sunshine. Nevertheless, the risk of summer storms is high and the average monthly rainfall exceeds 20 mm, making the last days of the month unpredictable.
Past eclipses
The last total eclipse visible from Onda took place on 30 August 1905, 121 years ago, with a totality phase of around three minutes. A few years earlier, on 11 November 1901, an annular eclipse also crossed the area. After the eclipses of 2026 and 2028, Onda will not see another total eclipse, though it will be able to observe an annular eclipse on 13 July 2075, with an obscuration of 87 %.
Direction and altitude of the Sun
At the moment of maximum, on 12 August 2026 at 20:31, the Sun will be just 4.6° high above the horizon, practically at ground level in the west-northwest direction (azimuth 286°). At such a low elevation, the atmosphere thickens the layer of air through which light passes, but it also increases the risk that hills, buildings or trees to the west could intercept the line of sight. Choosing an elevated point with a clear view towards the west turns out to be decisive to not miss totality.

01
The eclipse from Onda
In Onda, totality began at 20:31 local time and lasted 1 min 28 s, until 20:33. The eclipse maximum fell at 20:32.
In Onda, the Sun was 5° above the horizon, toward the WNW. It sat right at the edge of the horizon: even a small nearby obstacle could have blocked it.
This area typically sees around 14% median cloud cover at that hour, based on ten years of historical data — not a forecast for this specific eclipse.

What the contact points (C1-C4) mean
A solar eclipse is described by four key moments, the contact points between the discs of the Sun and the Moon:
- C1First contact: the Moon touches the edge of the Sun and the partial eclipse begins.
- C2Second contact: the Moon fully covers the Sun and totality begins.
- C3Third contact: the Sun reappears and totality ends.
- C4Fourth contact: the Moon leaves the Sun's disc and the eclipse ends.
Where the eclipse is only partial, the Moon never fully covers the Sun: only C1 and C4 occur, with no totality in between.

Frequently asked questions about the eclipse in Onda
Was the eclipse of August 12, 2026 visible from Onda?
Yes, but marginally: with 100% obscuration, the topographic horizon from Onda was very close to the Sun's altitude at the end.
What time was the eclipse maximum in Onda?
Maximum occurred at 20:32 local time (18:32 UTC) in Onda.
Which direction was the Sun in during the eclipse from Onda?
The Sun was toward the WNW (azimuth 286°), 5° above the horizon at maximum from Onda.
How long did totality last in Onda?
Totality lasted 1 min 28 s in Onda (C2 to C3). (corrected for the Moon's limb profile)
Was Onda a good place to watch the eclipse?
Onda saw totality (C2-C3) very close to the western horizon. The partial end (C4) fell below the horizon: a clear western view was needed for an epic experience.
Do I need special glasses to watch the eclipse?
Yes, you need ISO 12312-2 certified eclipse glasses during every partial phase. Regular sunglasses do NOT protect. Glasses can only be removed during the totality phase (when the Sun is fully covered); never during annular or partial eclipses. Pages flagged "visible" assume a clear horizon, not a viewing recommendation.
