About Irun
Irun is a municipality in the Basque Country located at the far eastern edge of Gipuzkoa, on the border with France, on the banks of the Bidasoa River. With almost 62,000 inhabitants and an altitude of 23 metres above sea level, it is one of the main cross-border gateways of the Iberian Peninsula. Founded in 1776, the city combines its industrial and commercial character with a unique geographic position at the limit between two countries.
For this eclipse
On 12 August 2026, Irun will experience a partial solar eclipse. Maximum obscuration will occur at 20:26, with the Sun at 7.5 degrees above the horizon and a clear margin of 6.6 degrees: visibility is assured from unobstructed points to the west-northwest. Since the Sun will be low in the late afternoon, it is advisable to choose a clear location in that direction to take advantage of the phenomenon without buildings or hills blocking it.
The weather in August
August in Irun is characterised by low storm risk, which favours outdoor observations. Proximity to the Cantabrian Sea brings humidity and moderate temperatures typical of the Atlantic climate, without the heat extremes of the interior peninsula. Data from the reference AEMET station (1012P, period 1991–2020) confirm this trend of atmospheric stability in summer, with few episodes of persistent cloud cover in August.
Past eclipses
The last annular eclipse visible from Irun occurred on 1 April 1764, approximately 262 years ago, with an obscuration of 86.9 % and an annular phase of just over five minutes. Since then, no total eclipse has crossed the city. The next annular eclipse to be seen from here will occur on 27 February 2082, with an obscuration of 84.5 % and an annular duration of just over six minutes.
Direction and altitude of the Sun
At maximum eclipse, the Sun will be at 7.5 degrees above the horizon, pointing towards the west-northwest with an azimuth of 283 degrees. It is a low but sufficient position for comfortable observation from a flat or elevated point without obstructions in that direction. The Basque afternoon in August prolongs daylight, and at 20:26 the Sun will be clearly above the sea horizon line.

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.

Do I need special glasses to watch the eclipse?
