Guam is located in Australia and Oceania. The country is washed by the Pacific Ocean. Guam is a small country. To determine the temperature of water in it, we track only ten settlements or resorts.

Tropical marine, trade wind. Guam’s climate is warm and humid, almost all year round the air temperature is around + 25-30°C (the warmest period is from May to July), while the daytime temperature ranges from + 28°C to + 33°C, and night - from + 23 ° С to + 25 ° С. Only during the period of influence of the northeast trade winds (from July to November) is there a slight decrease in temperature (up to + 22-27 ° С). Precipitation is up to 2000 mm per year, while the average air humidity all year round leaves about 78-82%. Two seasons are clearly distinguished: dry “fanumnangan» (fanumnangan, from December-January to June) and rainy “fanunchanan» (fanuchanan, from July to December). The Mariana Islands are in the zone of origin of typhoons, which are gaining strength already having passed the line of the archipelago. However, from June-August to November-December, periods with strong winds and storms are not uncommon.
