Eclipse Weather Prospects

A very detailed analysis of prospective weather conditions for solar eclipses is published on by Jay Anderson. We acknowledge his invaluable contribution to successful eclipse observing over many years. Here is the relevant part of his article on the 2019 total eclipse.

"Inland, beyond the reach of the low-level marine stratus cloud, the rugged terrain is both a good cloud manufacturer and a cloud eater. As the prevailing westerly winds rise over the peaks, the air cools by expansion and condenses into clouds. Conversely, on the downwind side of the terrain heights, air descends into valleys, warming and drying by compression as it sinks. The ups and downs of cloudiness caused by these alternating ascents and descents are prominent features of the cloudiness depicted in Graph 1 and in the graph.

All the available evidence – satellite and ground-level measurements – points to a location up against the eastern slopes of the Andes as having the best chances of seeing the eclipse. In particular, the small hamlets of Bella Vista and Iglesias (north of Bella Vista) lie on an open plain where satellite imagery shows the lowest average cloud amount anywhere along the track. Bella Vista is an 80 km trip from San José de Jáchal through rising terrain, but the village itself is on an open plain with good visibility west toward the lowering Sun (11° high at mid-eclipse). The highway is paved to Bella Vista."
