If you're looking to travel in August, I'd recommend considering destinations that are a bit cooler since it's usually one of the hottest months of the year. I've heard great things about the Pacific Northwest in the US, places like Seattle or Portland, they have a really nice mild climate during August. Alternatively, if you're open to traveling further, Europe has some amazing spots like the Scottish Highlands or the Irish countryside, which are beautiful during this time of year and the temperatures are quite pleasant. Just keep in mind that August is peak tourist season, so book ahead to avoid any hassles.
