Yes, the occurrence of seasons does have an impact on the weather and climate system of the Philippines.
Key ways that seasons impact the weather and climate in the Philippines include:
Monsoon winds - The Philippines experiences two monsoon seasons: southwest monsoon (wet season) and northeast monsoon (dry season). The monsoon winds bring different weather conditions during each season. The southwest monsoon brings rainfall while the northeast monsoon brings relatively little precipitation.
Monsoon precipitation - Around 95% of the Philippines' rainfall occurs during the southwest monsoon season from May to October. This monsoon rain results in flooding and landslides, especially in mountainous areas. The northeast monsoon from November to April brings much less rain.
Typhoons - The Philippines lies in the western Pacific typhoon belt. Most typhoons hit the Philippines during the southwest monsoon season from June to November. Typhoons can bring intense rainfall, strong winds, storm surge, and flooding.
Temperature - In general, the dry season has greater temperatures than the rainy season does. In the summer, daytime highs are often 32-34°C (90-93°F) and in the winter, 28-30°C (82-86°F).
Humidity - During the rainy summer months, humidity is high (about 80%), while it drops to only 60 to 70% during the dry winter months.
In conclusion, it can be said that the seasonal cycles of winds, precipitation, temperatures, humidity, and typhoons significantly affect the weather and climatic pattern across the Philippines. In the Philippines, the difference between the wet and dry seasons is particularly noticeable.
