Luckily, for those planning a trip, you'll find that daytime and evening temperatures in Tahiti, as well as throughout the entirety of French Polynesia, are incredibly stable from month to month. You'll see on the temperature chart below that each day of the year is almost identical to the other days. Moorea Island is only 9 miles (17 km) away, so the climate and weather are basically identical, and there are better Moorea overwater bungalow resorts to consider as well.
Because these averages are so reliable, you don't need to worry about checking the forecast during the days leading up to your trip. The highest recorded highs are only a tiny bit above the average, and it's the same story with the record lows.
