Looking at weather reports for CVO on the internet - is it really 34 degrees at the moment and is this normal and expected to last - coming over on Sunday.

On the Carvoeiro.com home page click on WeatherStat under Popular links on the left side of the page and then click on Portimao for weather forecast. It is hot at the moment and judging by the forecast on the above link there may be showers in next 2/3 days but these generally never materialise.
