What’s the weather like in Hawaii in May?
The islands of Hawaii are located in the Pacific Ocean, with a tropical climate bringing hot sunny weather to the region all year round. The summer months, including May, June, July and August, are the driest of the year, so it’s unlikely you’ll experience much wet weather. Despite the great weather, May is one of the quieter months in Hawaii so this is a good month to visit if you want to avoid the crowds.
The average temperature in Hawaii in May is a warm 25°C, with highs of 27°C and lows of 22°C. UV levels are high at this time of year so you’ll need to apply sun cream regularly, seek shade and stay hydrated, especially in the hottest part of the day. Just 40mm of rain is expected in May, with the majority of showers falling over higher ground. For days at the beach, each day has around 11 hours of sunshine at this time of year, with the Pacific waters measuring a balmy 25°C, perfect for swimming and surfing.
