No change from the mostly uninticing July weather, although rainfall should start to lessen towards the end of August. Wherever you travel in Myanmar at this time of year, you should expect heavy rain for the majority of days.
Temperatures during August remain high (averaging highs of 27-30°C) however the beaches on Myanmar's west and southern coasts are still closed; with resorts boarded up to protect them from the large waters clattering in from the Bay of Bengal and the Andaman Sea.
Heavy rainfall can make road travel across parts of the country difficult, especially in the more rural and remote areas of the country where roads may be impassable.
Can you still travel in Myanmar in August Yes, just about. Are there better months to visit? Without question!
