Climate zone: tropics
High humidity in Federated States of Micronesia and high temperatures are causing a pleasant weather at times, but also and partly tropical hot and humid. It is warm to hot all year round and invites to bathe at average water temperatures of 27 degrees. Dued to the lesser rain the best time for traveling is in February.

Temperature records of the last 70 years
The hottest temperature measured from 1949 to December 2019 was reported by the Yap weather station. In March 2013 the record temperature of 39.6 °C was reported here. The hottest summer from July to September, based on all 2 weather stations in Micronesia below 40 metres altitude, was recorded in 2016 with an average temperature of 28.6 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 27.5 degrees Celsius. The average maximum daily temperature at that time was 31.8 °C.
The coldest day in these 70 years was reported by the weather station Yap. Here the temperature dropped to 17.2 °C in November 1999. Yap lies at an altitude of 15 meters above sea level. The coldest winter (January to March) was in 1993 with an average temperature of 26.8 °C. In Micronesia, it is usual to have about 0.7 degrees more at 27.5 °C for this three-month period.
Long-term development of temperatures from 1997 - 2019
In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 2 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1997 to 2019 there were only these 2 weather stations in the whole country, which reported continuous temperature values (Chuuk, Yap). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was April 2016 with 29.2 °C. August 1999 was the coldest month with an average temperature of 26.5 °C.
The average annual temperature was about 27.6 °C in the years after 1997 and about 28.3 °C in the last years before 2019. It has therefore increased only slightly by about 0.7 °C over the past 23 years. This trend only applies to the selected 2 weather stations in Federated States of Micronesia.
