Colors of the following climate diagrams: Thailand Philippines
Daily maximum temperatures
The highest daytime temperatures in the Philippines are reached in May with an average of 33.4 °C. The coldest month, on the other hand, is January, with an average of just 30.2 °C. In Thailand, April is the warmest month, with 35.5 °C. There, it is coolest in December with an average of 31.0 °C.
Night time lows
At night, it cools down to varying degrees depending on the country and altitude. In the Philippines, temperatures drop as low as 22.5 °C in January. The warmest nights are in May at 25.0 °C. In Thailand, it is coolest at night in January at 20.7 °C and warmest in May at 25.8 °C. This corresponds to a cooling of 7.4 to 8.9 °C in the Philippines and 7.7 to 10.7 °C in Thailand.
The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.
Humidex is an approximate, sensed temperature calculated on the basis of air temperature, dew point and humidity. It was developed in 1965 by the Canadian meteorologists J. M. Masterton and F. A. Richardson. Since the wind speed is ignored here, it is not very meaningful in areas below approx. 15°C. Above that, it is more reliable, since at higher temperatures humidity plays a greater role than wind.
Rain days per month
By definition, a rain day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. July brings the most rainy days (15.7) in the Philippines. With an average of only 6.2 days, April is the friendliest. In Thailand, it rains most often in September with 16.4 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in the Philippines occurs in August, when about 8.9 liters per square meter fall per day. In Thailand, the average amount of precipitation ranges from 1.0 liters per day in February to 10.2 in September. However, these are average values. If you consider that there are only 14.9 rainy days in the Philippines in August, each of them accounts for about 18.0 liters.
Sunshine hours per day
With 2,336 hours of sunshine per year, Thailand is in the lead. The most hours of sunshine (8.2 per day) are in February. The Philippines falls into second place with only 2,300 hours. There the sun is visible in December for only 5.3 hours per day, so not hidden behind clouds.
