In August, you should expect a weather that's mostly hot and sunny. Starting from La Línea de la Concepción and going inland, you'll mostly have sunny days. Sometimes, there might be some clouds or it could be overcast, giving you a break from the sun.
As you move from the coast to the inland areas of Andalucía, it will usually get hotter. The temperature starts at around 28°C on the coast and can go up to 37°C-38°C in places like Coripe, Montellano, and Sevilla. During the night, it gets cooler with temperatures in the low to mid-20s in most places.
The route is usually dry with little rain on average. However, sometimes there can be light or heavy rain. These rains don't usually change the overall dry weather of the route. So, in general, you should expect a hot, sunny journey with occasional clouds or rain.
