August on the Camino Francés is high summer: long sunny spells and strong afternoon heat across much of the route. Skies are often clear or partly cloudy, with only isolated days of showers or a passing thunderstorm in the drier east. Temperatures run warm to very hot on the plains, while higher passes and the far northwest feel noticeably cooler and more changeable. Inland air is usually dry, and humidity rises toward the Atlantic side where cloud and mist are more common. Winds are mostly light, though exposed stretches can see a steady afternoon breeze. Nights cool off inland but stay milder and a bit damper under the ocean influence. Overall it’s a bright, mostly dry month with brief interruptions from stormy bursts, especially near hills and in the western regions.
Packing list for Camino routesThe month often starts with the Pyrenean crossing under mixed skies: low cloud and mist can hug the ridge, with light drizzle or a passing shower and a cool, sometimes blustery feel. As you descend into the basins, the weather settles into broad sunshine and quick warming, with afternoons that are generally warm to hot. Most days are dry, but brief showers or an isolated thunderstorm can pop up, usually clearing fast. Nights bring some relief, and morning cloud can linger before giving way to sun.
Across the open valleys and vineyards, August turns hotter and drier with long, bright days and strong sun. The prevailing pattern is stable and dry, punctuated now and then by a short-lived shower or late-day thunderstorm. Winds are usually light, and haze can build in the heat. Overall it feels hot to very hot, with warm evenings.
Out on the meseta, skies are often clear at dawn and stay mostly sunny through the day, with heat building steadily by afternoon. Rain is scarce, but brief showers or a local storm can break the spell, then fade quickly; a steady afternoon breeze is common on the exposed stretches. Overall it feels hot to very hot, with cooler nights that can refresh. Climbing into the Montes de León, temperatures ease with more cloud and a chance of light rain or drizzle, before the Bierzo valley turns warmer and slightly more humid with occasional showers.
The high entry ridge is frequently cloudy or misty, with light drizzle at times and a cooler, breezier feel than the plateau behind you. As you drop into inland Galicia, the pattern turns changeable: sun and cloud trade places, with many dry hours but periodic light rain or a passing shower. Humidity is higher, and morning fog is common before brighter breaks arrive. Overall it runs mild to warm, with the Atlantic influence bringing the risk of a heavier burst in between longer settled spells.
