2027 Eclipse Weather Analysis: Where to Go for Clear Skies
Weather is the single biggest variable in eclipse observing, and the 2027 eclipse benefits from occurring during the height of the dry season across almost its entire land path. Unlike the 2026 eclipse (which occurs at sunset with low-altitude cloud risks), the 2027 eclipse takes place in the late morning with the Sun high in the sky, giving you a shorter atmospheric path and less susceptibility to horizon cloud. Here is a detailed weather analysis for each major region along the path of totality, based on historical satellite data from the European Centre for Medium-Range Weather Forecasts (ECMWF) and national meteorological agencies:
Southern Spain (Seville, Cadiz, Gibraltar)
Southern Spain has the best weather of any European eclipse destination in summer. The average cloud cover at 11:00 local time on August 2 in Seville is approximately 25-30%, meaning a 70-75% chance of clear or mostly clear skies. The region is influenced by the Azores High pressure system, which typically brings stable, dry conditions in July and August. The main weather risk is the Calima — suspended Saharan dust that can create a hazy sky even when technically "clear." However, the Calima is more common in winter and spring than in August. Gibraltar's proximity to the Strait of Gibraltar can create local cloud formations due to the Levanter wind, but these typically dissipate by mid-morning. The best locations in Spain are inland (Seville, 30-50 km from the coast) where sea breeze effects are minimised.
Morocco (Tangier, Rabat, Casablanca)
Morocco's Atlantic coast has a slightly higher cloud risk than inland areas due to morning coastal fog (the "camanche" in Arabic). Historical data shows that Tangier has a 30-35% cloud cover probability at 11:00 local time in August, with most of that being thin coastal stratocumulus that typically burns off by 09:00. The best strategy in Morocco is to choose a location 30-50 km inland from the coast, where the fog influence is negligible. The foothills of the Rif Mountains offer excellent viewing sites with clear skies, elevated perspectives, and dramatic landscapes. The region around Chefchaouen and the Talassemtane National Park provides both guaranteed clear skies and stunning natural scenery.
Algeria, Tunisia & Libya
The North African coastal strip from Algiers through Tunis to Tripoli has some of the best weather prospects on the entire eclipse path. August is the peak of the Mediterranean dry season, and historical satellite data indicates less than 20% average cloud cover at 12:00 local time across this region. Inland areas (50-100 km from the coast) approach 5-10% cloud cover, making them among the most reliable locations on Earth for eclipse viewing. The Sahara Desert, which begins just south of the coastal cities, offers virtually guaranteed clear skies, though travel logistics become more challenging. For eclipse chasers prioritising weather certainty above all else, the desert regions of southern Tunisia or northern Algeria are the optimal choice.
Egypt & Saudi Arabia
Egypt's Mediterranean coast (including Alexandria) benefits from the same dry summer pattern as the rest of North Africa, with 15-20% cloud cover probabilities. The Nile Delta region has a slight risk of morning haze due to evaporation from the river and irrigation canals, but this typically clears by 09:00. The best viewing locations in Egypt are west of Alexandria along the Mediterranean coast or south toward the desert where humidity drops sharply. Saudi Arabia's portion of the path covers the Medina region and the Red Sea coast, where August cloud cover is typically below 10%. The desert climate guarantees virtually cloud-free conditions, though the extreme heat (40-45°C) requires careful planning and hydration. The high altitude of the Sun in North Africa (60-75 degrees) means you are looking through minimal atmosphere, providing the sharpest possible telescopic views of the corona.
