About Guía de Isora
Guía de Isora is a municipality in the southwest of Tenerife, in Santa Cruz de Tenerife province, within the Canary Islands. Situated at 594 meters above sea level, the municipal territory descends from the slopes of Teide down to the Atlantic coast. With just over 20,500 inhabitants, it combines rural zones in the middle elevations with coastal settlements such as Playa de San Juan and Alcalá. Its western position on the island and its moderate altitude give it a singular climatic character within the archipelago.
For this eclipse
On August 12, 2026, Guía de Isora will witness a partial solar eclipse. Maximum will occur at 19:54, local time, when the Sun will be 11 degrees above the horizon and at an azimuth of 281 degrees, a direction corresponding to west-northwest. With a margin of more than 12 degrees above the topographic horizon, the celestial body will be perfectly visible from middle elevations and unobstructed zones toward the west. The fraction of the solar disk that will be covered will be notable, though there will be no totality.
The weather in August
Southwest Tenerife, the zone where Guía de Isora is located, falls under the influence of the trade winds and sheltered by the Teide massif, which generates a drier and sunnier microclimate than the north of the island. During August, the risk of thunderstorms in this municipality is low according to records from the AEMET station corresponding to the area, which favors conditions for observing the sky. It is a month of moderate heat in the middle elevations, with scarce cloud cover during the central hours of the day.
Past eclipses
Guía de Isora has not seen a total solar eclipse since October 27, 1780, now 246 years ago, when totality lasted barely 52 seconds over the Canary Islands. Before that, on April 1, 1764, an annular eclipse crossed the region. After the partial eclipse of 2026 and those arriving in 2027 and 2028, one must wait until July 6, 2187 for totality to once again cover this corner of the Atlantic.
Direction and altitude of the Sun
At the moment of maximum coverage, at 19:54, the Sun will be in a low but clear position: just 11 degrees high and at an azimuth of 281 degrees, practically toward the west-northwest. To orient oneself, one need only look toward where the sun sets in summer, slightly north of the west position. From elevated zones of the municipality without buildings to the west, the view will be clear and the eclipse will be completely observable.

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.
