Ha ha! Yes. It is a well known phenomenon that it rains continuously in Scotland during the school holidays. Much better the rest of the year. Disagree about the colours in August though, late august is when the main cover of heather blooms and the colours are magnificent.
To the poster who advised the OP to ignore stalking signs- it is attitudes like that which can make the relationship between stalkers and hillwalkers very awkward. A hill walker may be within their rights to walk on the main paths, burnsides and ridges during the stalking season, but ignoring signs completely can interfere with legitimate land managment activity. I try to contact estates before hand to discuss routes, or use the Hillphones system where available.
Midgeswise: As already said, August will probably be hell if you are camping for any length of time. Coastal areas can be breezier so sometimes better, but only if there is wind. If not camping you'll be fine.
