Best time to visit Monkey Mia

April to OctoberAnd the dolphins come in all year.

Any month for the dolphins, and April to October for the most comfortable days. The wild dolphins come into the shallows at Monkey Mia most mornings all year round, so the season is about the weather around them. Denham averages 29°C in April and 26°C in October, with 22 to 23°C days from June to August, and September to December is almost rainless, at 2 to 8mm a month. October to April is swimming weather, peaking at 32°C in February. Four days from Perth, with a night at the dolphin resort on the beach, is from $1,299.

Monkey Mia is on Shark Bay, a long way up the coast from Perth, and it is warm and dry for most of the year. The dolphins do not keep a season, so there is no wrong month to go. The real choice is between swimming weather and walking weather.
