Weather in San Jose

Stay updated on the meteorological conditions in San Jose. Below you will find the latest data, charts, and a detailed forecast for the coming days.

The climate in San Jose can be described as classic tropical, characterised by hot and humid weather. One of the main features of the region is the remarkable stability of temperatures: throughout the year, the thermometer stays within a comfortable range of +26°C to +28°C, rarely dropping below +24°C even at night. Eternal summer reigns here, so you are unlikely to need warm clothing.

Two distinct periods can be observed in the weather calendar, depending on the amount of rainfall. The most favourable time to visit is the dry season, which lasts from January to April. During these months, rain is extremely rare and minimal in volume, creating ideal conditions for beach holidays and walks under the bright sun. April is traditionally considered the hottest month, when the air warms up to +30°C.

With the arrival of May, the picture changes: the long rainy season begins and continues until the end of the year. The peak of precipitation falls between June and October, when there are more rainy days than sunny ones (in July, for example, it can rain almost daily). Nevertheless, even during the season of downpours, high air temperatures persist in San Jose, creating a "sauna-like" effect typical of the tropics.

The climate in San Jose is distinguished by enviable stability, typical of tropical latitudes. It is practically eternal summer here, and sharp temperature fluctuations are not observed during the year. Average thermometer readings confidently hold in the comfortable range of +26°C to +28°C, making the city attractive for travellers seeking warmth, regardless of the month chosen for the trip.

The hottest period is traditionally April and May, when daytime temperatures reach their peak, rising to +30°C. At this time, the air warms up to the maximum, creating the sensation of true tropical heat. The so-called "winter," occurring in January and February, brings only barely noticeable coolness: the average temperature in these months drops to +26°C, and night-time minimums rarely fall below +24°C, which is still considered very warm weather by most standards.

It is noteworthy that there is practically no significant contrast between day and night in San Jose. The amplitude of temperature fluctuations is small and usually amounts to just 2–4 degrees. Even in the rainy season, which lasts from June to October, the warmth remains: despite the high humidity and precipitation, the thermometer consistently shows around +27°C, creating a soft and warm atmosphere around the clock.

When travelling to San Jose, it is important to consider the nature of precipitation, which has a clearly defined seasonality here. Throughout the year, the weather changes from dry and clear months to periods with frequent rains, which is typical for the Philippine climate. There is no snow here, so the main type of precipitation is tropical rain of varying intensity.

Lovers of sunny weather should plan their trip for the first half of the year. The period from January to April is characterised by a minimal amount of moisture. The driest month is February, when rains occur extremely rarely (on average about 8 days with precipitation), and their volume barely reaches 1 mm. This is the ideal time for beach relaxation and long walks in the open air.

The rainy season begins in June and lasts approximately until October. During this time, an umbrella will become your mandatory companion: the number of days with precipitation increases sharply, reaching a peak in July (up to 30 rainy days). Despite the high frequency of rains, their average monthly volume remains comparatively small (a maximum of 19 mm in July), which often indicates regular but not overly heavy rainfall that brings freshness on hot days.

When planning a trip to San Jose, prepare for the warm tropical climate that prevails here all year round. The basis of your luggage should be light items made from natural breathable fabrics: cotton, linen, or viscose. T-shirts, shorts, loose-fitting trousers, and summer dresses will be the most comfortable choice with an average air temperature of around +26...+28°C. Do not forget comfortable open footwear for long walks and a head covering to protect against the active sun.

Particular attention should be paid to the rainy season, which is most pronounced from June to October, when precipitation can fall almost daily. During this period, a high-quality raincoat or a compact, sturdy umbrella are mandatory items on your packing list. Since it is warm outside even in rainy weather, warm clothing will not be required, although a light windbreaker may be useful for protection against the wind or the coolness in air-conditioned rooms and transport.

At any time of the year in the Philippines, reliable protection against ultraviolet radiation is necessary. Be sure to take sunscreen with a high SPF factor and sunglasses, even if the forecast promises cloudiness. Given the high humidity, clothes may dry longer than usual, so we recommend taking a sufficient number of fresh changes of underwear and t-shirts to always feel comfortable.
