Top 3 Things You Need to Know About January Weather

2015 is here! Another year, another set of goals. But before we outline our plans for the new year, let us first familiarize ourselves with this month’s weather.

1) Rains won’t go away yet.


This month marks the start of another year but rainy days won’t end yet for some areas of the country. PAGASA Weather Forecaster Buddy Javier said the northeast monsoon or amihan and the tail end of a cold front will be dominant. Amihan is cold and dry air coming from Mainland China or Siberia, bringing light rains mostly over Northern and Central Luzon.

Meanwhile, the tail end of a cold front refers to the extended part of a cold front which is formed when the cold air mass dominates the warm air mass during a convergence. Javier added that at this time, Southern Luzon usually experiences cloudy skies, as well as light and moderate to occasionally heavy rain showers and thunderstorms. However, the tail end of a cold front can recede or move, depending on the strength of amihan.

2) January’s not totally “bagyo-free”.

According to PAGASA, the average number of tropical cyclones that usually enters the Philippine Area of Responsibility (PAR) this month is 0 to 1. This means that there is still a chance for us to experience stormy weather even in the first month of the year.

Climatologically speaking, a cyclone that may enter the PAR could cross the archipelago or make landfall, particularly over the Visayas area. It is also possible for it to re-curve, moving away from the landmass. The surge of the northeast monsoon or amihan influences its movement.

3) The much awaited sweater-weather is here.

Amihan peaks this month, bringing colder weather mostly over Luzon. Minimum temperatures are usually recorded during this chilly part of the year. One of the significant amihan-related events happened on January 18, 1961 when Baguio City’s temperature dropped to 6.3 degrees Celsius.
