Valls is a municipality of some 25,000 inhabitants located in the Camp de Tarragona region, province of Tarragona, in Catalonia. At an altitude of 223 metres above sea level, the city occupies the centre of the Francolí river plain, surrounded by vineyards and almond groves. Internationally recognized for its tradition of castellers—the human tower formations declared an Intangible Heritage of Humanity—Valls acts as a service hub for inner Tarragona.
On 12 August 2026, Valls will lie in the path of totality of the solar eclipse. The moment of greatest obscuration will arrive at 20:29 local time, when the Sun will already be very close to the western horizon, at just 4.4 degrees above the horizon. This position leaves a margin of barely 1.2 degrees over the topographic horizon, making the visibility of totality marginal: any natural or artificial obstacle to the west-northwest could prevent seeing the minutes of the solar corona. It is recommended to seek an elevated location with a clear horizon in that direction.
August is the warmest month of the year in Valls. The average temperature hovers around 24.7 °C, with highs that regularly reach 30.9 °C during the day and lows of 18.5 °C at night. Precipitation is scarce—around 24.7 mm average monthly—but the risk of convective thunderstorm is moderate: the hot afternoons of inner Catalonia can generate towering cumulonimbus clouds that would cloud the view in the hours before the eclipse. Data: AEMET, 1991–2020 series.
Valls has memory of great eclipses. On 8 July 1842—184 years ago—the city witnessed a total solar eclipse with approximately one minute of totality, one of the most remembered astronomical events of the 19th century on the Iberian Peninsula. The last annular eclipse dates from 11 November 1901, 125 years ago. After the 2026 eclipse, one must wait until 13 July 2075 to see an annular eclipse, and until 17 November 2180 for the next total.
At the moment of maximum eclipse, the Sun will be positioned at an azimuth of 286 degrees—almost due west, with a slight tilt towards the northwest—and at just 4.4 degrees above the horizon line. This height is roughly equivalent to the width of four fingers held at arm's length. The Sun will descend rapidly towards sunset, so the eclipse will unfold with an orange-coloured ambient light characteristic of dusk and a very low horizon.

A solar eclipse is described by four key moments, the contact points between the discs of the Sun and the Moon:
Where the eclipse is only partial, the Moon never fully covers the Sun: only C1 and C4 occur, with no totality in between.

Solar eclipses computed from astronomical ephemerides for the city's coordinates.
Yes, but marginally: with 100% obscuration, the topographic horizon from Valls is very close to the Sun's altitude at the end.
Maximum occurs at 20:29 local time (18:29 UTC) in Valls.
Look WNW (azimuth 286°); the Sun will be 4° above the horizon at maximum from Valls.
Totality lasts 0 min 44 s in Valls (C2 to C3).
Valls will see totality (C2-C3) very close to the western horizon. The partial end (C4) falls below the horizon: you need a clear western view for an epic experience.
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.
For the August 12 eclipse. Recommended stay: Aug 10–14, 2026.
