Temperatures are forecast to drop back to 18 or 19 degrees Celsius next week. The return of warmer weather will be accompanied by a shift in the weather pattern, bringing with it rain and drizzle. Forecasters advise enjoying the sunshine while it lasts, as more unsettled conditions are on the horizon. This follows a period of changeable weather, and the return to rain is typical for the season.
