Portugal is a great destination for a holiday with its stunning landscapes, vibrant culture and mild climate, making it a great choice for British tourists looking to explore in May. We've looked at the most up-to-date weather data for Portugal, covering the last 12 years up to 2024, plus we've asked our team of travel bloggers for their first-hand experiences in order to answer the most frequently asked questions about Portugal weather in May.

How warm is it in Portugal during May?

The temperature reaches around 24℃ during the daytime in May, falling away to 12℃ at night. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in Portugal during May?

On average, there will be 3 rainy days during the month, amounting to 47.9mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. There's a small chance that you'll catch a thunderstorm during your trip.

Is it windy in Portugal during May?

You're unlikely to experience any strong winds. Expect a light breeze that picks up slightly at times in May. With moderate humidity and mild air temperatures, the breeze will have a slight cooling effect.
