A summary of the weather over the last 10 days of May : it has been around 23° - 24°C most of the time although a little cooler on the Monday. We have had some showers but mostly overnight or first thing in the morning - the afternoons have been warm and sunny. One exception was a week ago on the Friday when it rained heavily all afternoon (that's the polite version of my diary entry!). 
The last few days have been dry, warm and sunny and today is no exception - a lovely start to June here in the Algarve.
