Saint Helena is located in South America. The country is washed by the Atlantic Ocean. Saint Helena is a small country. To determine the temperature of the water in it, we monitor only one locality.

Tropical marine. The average monthly temperature ranges from + 19°C (January) to + 30°C (July), while the general temperature background is quite uniform, even in winter a drop in the thermometer column below + 13°C is a rare occurrence. However, subjectively it always seems a little colder than it actually is, which is caused by moist ocean air, constant winds and frequent fogs. Precipitation falls from 400 to 1500 mm per year, December and January - the wettest months of the year.
