Rank 47 of 105 along the path
Index = 100·(0.5294·duration + 0.2941·sky + 0.1765·view). Duration normalised against 240 s; view normalised logarithmically over the ray-march range. The horizon margin does not weigh in 2027: it comes out identical across all 105 municipalities.

How long totality lasts in Rota
Totality in Rota lasts 2m 10s. Of the 105 Spanish municipalities inside the path, 56 get a longer one and 47 a shorter one, which puts Rota in the 45th percentile of the path. The longest stretch in Spain is Ceuta, with 4m 48s, and the shortest Casarabonela, with 10s.
The path of totality is about 238 km wide as it crosses southern Spain. Rota sits roughly 111 km north of the centre line and about 7.4 km from the north limit of totality: driving that far north would drop you out of totality and into a partial eclipse. Going south, on the other hand, lengthens it.
At 2m 10s, Rota sits in the middle third of the path: far more than a blink, well short of the Spanish maximum. Decide beforehand what you want to look at, because there will not be time to improvise twice.
Timings and duration: Instituto Geográfico Nacional. Path width and distance to the centre line: computed from the two published limits of the path of totality.The Sun, the shadow and the terrain
Maximum eclipse reaches Rota at 10:46:40 mainland Spanish time. The Sun will be 37° above the horizon at azimuth 95°, that is, towards the east. The magnitude of the eclipse will be 1.07.
That altitude is the deep difference from the 2026 eclipse, which happened with the Sun almost touching the horizon and the terrain to the west deciding who saw totality and who did not. Mid-morning on 2 August the problem disappears: in Rota the margin between the Sun and the terrain profile in that direction is 37.2°, and across the whole path the tightest margin is Benalauría, at 27.8°. All 105 municipalities clear the visibility test.
The shadow, however, does not arrive from where the Sun is: the umbra comes in from the west-southwest (256°), crossing in from the Atlantic. From Rota the line of sight in that direction runs 23 km unobstructed, so there is room to watch the shadow arrive as a front sweeping over the landscape: it is one of the most striking moments of the whole event and plenty of people miss it by looking only upwards.
The sky at eclipse time, from 30 years of data
Across the 1996-2025 series, the sky over Rota was clear during the 10:00-11:00 window —the hour that brackets maximum— in 86.7 % of years. Under a stricter test, less than 20 % cloud cover, the figure is 86.7 %; under 10 % cloud cover, 83.3 %.
The whole-day average gives 93.3 %, clearly better than the eclipse window, and that gap is not noise: mid-morning the low cloud off the Strait and the coast has not burned off yet, and it does so as the morning wears on. In that hour the mean low cloud over Rota is 5.7 %. That is why this page publishes the window figure rather than the daily one: the daily average paints a sky that does not exist yet at eleven in the morning.
The mean maximum temperature for 2 August in this grid cell is 30.6 °C and the mean minimum 21.7 °C, and it rained in 3.3 % of the 30 years. None of this is a forecast: it is climatology, an answer to what is normal here at that hour, not to what the weather will do on the day.

Rota scores 68.4 out of 100 on the observing index for this eclipse and ranks 47 of 105. The index weighs three things measured on the spot: the duration of totality (52.94 %), the sky in the window around maximum (29.41 %) and the line of sight in the direction the shadow arrives from (17.65 %).
Its three components, normalised from 0 to 1, come out at 0.542 for duration, 0.890 for sky and 0.766 for view. The one pulling hardest upwards is the sky; that is what this town has going for it.
The index ranks the path; it does not replace a forecast. It also knows nothing about access, parking or permits: that fourth component was in the design at 15 % and is not published because the dataset does not exist, so the other three are renormalised rather than padded out with an invented estimate. The horizon margin, which carried 30 % of the 2026 index, does not weigh here: with the Sun at nearly 40° it came out identical in all 105 municipalities.
