The Peruvian capital presented Cool mornings and gray skies, even though the official start of summer is just a few days awayaccording to detailed monitoring by the National Meteorology and Hydrology Service (Senamhi). Experts attribute this phenomenon to factors such as high humidity on the coast and persistent cloudiness, conditions that affect both the coast and other regions of the country.
The thermometers show values below twenty degrees Celsius different districts of Lima in the early hours of the morning, Many Lima residents feel that the climate is closer to autumn. As they wait for a sustained rise in temperatures, experts are observing similar patterns in several areas of the country, where low night temperatures continue to prevail on the coast and temperatures are increasing in mountainous and jungle areas.
In the first hours of the day, Lima is covered by fog and cloudy skies. According to Senamhi reports, this period is characterized by Prevalence of low temperatures, especially in areas far from the sea. In areas in the east and in the center of the city, the lowest temperatures reach fifteen degrees Celsius, while in coastal areas measurements show record values of eighteen to nineteen degrees. The phenomenon is attributed to persistent coastal humidity and cloud cover limiting the sun’s presence.

According to experts, the feeling of cold intensifies at dawn, even on the eve of summer. Factors like the increase in humidity and the influence of winds from the south contribute to maintaining these conditions. Cooling of the sea surface also affects the persistence of moist air and delaying the transition to true summer temperatures. Senamhi monitors in real time what is happening both in the capital and in other cities on the coast.
Although many Lima residents expect a drastic change at the start of summer, Senamhi makes this clear The transition will occur gradually throughout the month. Summer officially begins on December 21st, but the rise in temperatures will be gradual, with more significant increases towards the end of the month. The institution emphasizes that these changes do not occur suddenly, but rather respond to the seasonal behavior of the region’s climate.
This is what meteorologists point out Cloud cover and fresh air will also prevail in the next early morning hoursalthough the afternoons could feature warmer conditions and sunshine. Lima also has a diversity of microclimates, which is reflected in significant differences between districts near the coast and those further from the coast.
While it continues to be cold and cloudy in the mornings and evenings in Lima, the panorama in the mountains of Peru is different. The Senamhi has issued notices about this significant increase in daytime temperatures in several provinces of the northern, central and southern mountains, with record highs of up to 38 degrees Celsius, particularly in cities such as Cajamarca and La Libertad. Clear days and intense sunlight characterize this region during the day, while significant declines are recorded at night.

In the Peruvian jungle, the meteorological situation follows its own pattern. Heavy rains have recently been recorded in the central and southern jungles, while wind gusts continue to occur in areas such as Madre de Dios and Ucayali. Senamhi reports that these conditions can alter river flows and create additional variations in the Amazon’s microclimate. At the same time, the humidity in the highlands of the Andes is increasing, which favors the occurrence of isolated precipitation.
Senamhi warns that although summer is approaching, current climatic conditions justify observing precautionary measures. On cold mornings and evenings Citizens should try to wear warm clothing when going to work or doing outdoor activities. Those who work outdoors for hours in strong sunlight are recommended to wear long-sleeved clothing, wide hats and sunscreen to prevent skin damage.
In Greater Lima, regulations require government institutions to provide protective equipment for personnel exposed to the sun as part of hot season protocols. In addition, it is advisable to pay attention to weather warnings, as fluctuations in temperatures, humidity and cloud cover in the coming weeks could have an impact on the health and mobility of the population.
