What time is the 2027 eclipse in Cádiz?
Cádiz is inside the path of totality on 2 August 2027. The partial eclipse begins at about 09:40 local time, maximum is near 10:46 and totality lasts about 2 minutes 54 seconds at the reference coordinates.
| Partial begins | Maximum | Partial ends | Totality | Coverage |
|---|---|---|---|---|
| 09:40 | 10:46 | 11:59 | 2m 54s | 100% |
Historical cloud and heat context
For the three-hour window around maximum eclipse, the 2000 to 2025 ERA5 sample has 10.9% mean total cloud cover and 1.3% median cloud cover. 88% of the 26 annual samples averaged 20% cloud or less. Mean low cloud was 6.6%, relative humidity 50% and temperature 28°C.
This is reanalysis for the same date and local time in previous years, not a forecast for 2027. The figures describe a model grid cell and can miss local fog, dust, smoke or terrain effects.
How to choose a site near Cádiz
Cádiz has a strong historical cloud signal in the ERA5 sample, but its Atlantic exposure and constrained approaches still reward an early arrival and a backup site. Historical reanalysis cannot predict the event-day sea breeze, haze or local cloud.
- Confirm that the exact site remains inside totality; duration changes across the province.
- Arrive early enough to avoid depending on the final approach during peak traffic.
- Prioritise an unobstructed southeast sky and lawful public access.
- Compare the coast with inland alternatives when reliable forecasts become available.
Coordinates and calculation limits
The reference point is 36.5271°, -6.2886° using Europe/Madrid. Times are rounded to the minute and solar altitude is 37.4° at maximum.
Totality duration varies with exact coordinates. Recalculate the chosen observing point and recheck civil-time rules before travel. Only remove certified eclipse viewers during confirmed totality; filters remain required throughout every partial phase.
Sources and methodology
Astronomical circumstances use the published city dataset and NASA cross-checks. Weather statistics are reproducible Open-Meteo ERA5 reanalysis samples for 2 August 2000 to 2025, averaged over the three local hours centred near eclipse maximum.
