What's the Weather like in Algarve in May


May is an excellent time to visit the Algarve for those after moderate warmth and reliably dry sunny weather. At the region's capital, Faro, the daytime temperature reaches an average temperature of 18°C and a high of 23°C, while the temperature falls to 14°C during an average night. Temperatures do occasionally fluctuate significantly either side of the long-term mean, however, and highs in excess of 30°C are possible.


Rainfall is observed occasionally during May, but there are usually prolonged dry spells. When it does rain at this time of year, the rain is often quite heavy and thundery. The average rainfall at Faro in May is just 22mm, and rain falls on an average of 7 days out of a possible 31, compared to December which can recieve up to 100mm of rainfall, which falls on average 12 out of 31 days.

Throughout May the sky is relatively clear compared to January 1st where the sky is mostly overcast or cloudy 44% of the time, while in May the skies are only 21% to 25% cloudy throughout the whole month, so you can generally expect very clear skies if you are planning on staying in the Algarve at this time of year.

The probability of precipitation at this time of year is generally low. Over the entire year, the most commons forms of precipitation are moderate rain to a light drizzle, with the odd thunderstorm. Moderate rain can occur during May, but this is only around 15% likely.

Most of the time the wind is coming from the west and north-west at this time of year. Because the Algarve is by the Atlantic Ocean, it is prone to a gentle breeze throughout the year, which can be very beneficial during the summer season where temperatures can reach a blistering 28°C in August.
