If you plan to walk the Camino Portugués de la Costa in August, expect warm weather. This trail, from Porto to Santiago de Compostela, often has sunny days. The temperature is usually between the high teens and the mid twenties.
In Porto, where you start, it's mostly sunny. The average high temperature is 25°C and the average low is 16°C. As you get to Labruge and Póvoa de Varzim, it stays sunny but a bit cooler, with highs around 24°C. The weather is similar in Marinhas, Viana do Castelo, and Caminha, but sometimes you might have a bit of rain and clouds.
The weather changes a bit when you get to Spain and into Galicia, passing through places like Porto Mougás, A Ramallosa, Vigo, and Redondela. Mostly, it's still sunny, but there's more cloud and rain, especially in A Ramallosa. Temperatures range around the mid-twenties during the day and the mid-teens during the night.
The last part of your walk, through Pontevedra, Caldas de Reis, Padrón, and ending in Santiago de Compostela, can have more changes. It can rain a bit, and there are some cloudy days. But there are also lots of sunny days, and the average high temperatures are in the mid-twenties and lows in the mid-teens.
