As an extensive island world, the Philippines are dependent on many weather factors. The best known are the Pacific influences with typhoons on the east coast, which occur mainly from August to November.
The west coast, which results from the climate of the South Chinese Sea, is almost isolated from this. There are monsoon winds from June to October, which bring warmer but also humid air masses.
The central islands of the Visayas are largely isolated from the open sea by the other chains of islands in front of them. Here, the climate is more moderate, but still hot by European standards.
In the southern regions around Mindanao and the Zulu archipelago, however, it is hot and rather dry all year round.

Temperature records of the last 70 years
The hottest temperature measured from 1949 to December 2019 was reported by the Zamboanga weather station. In October 2006 the record temperature of 41.5 °C was reported here. The hottest summer from July to September, based on all 35 weather stations in the Philippines below 1500 metres altitude, was recorded in 1998 with an average temperature of 28.8 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 27.9 degrees Celsius.
The coldest day in these 70 years was reported by the weather station Basco. Here the temperature dropped to 11.6 °C in February 2014. Basco lies at an altitude of 166 meters above sea level. The coldest winter (January to March) was in 1963 with an average temperature of 24.0 °C. In the Philippines, it is usual to have about 2.1 degrees more at 26.1 °C for this three-month period.
Long-term development of temperatures from 1998 - 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 4 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1998 to 2019 there were only these 4 weather stations in the whole country, which reported continuous temperature values (Laoag, Dagupan, Mactan, Zamboanga). 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 Mai 1998 with 29.8 °C. Januar 2014 was the coldest month with an average temperature of 25.2 °C.
The average annual temperature was about 28.0 °C in the years after 1998 and about 28.0 °C in the last years before 2019. So it has hardly changed at all in the past 22 years. This trend only applies to the selected 4 weather stations in the Philippines. A considerably more comprehensive evaluation of the global warming
has been provided separately.
