Flooded streets, evacuated families, rivers out of control! Northern Peru is not finding any rest. After heavy rainfall in Tumbes and Piura, more thunderstorms are threatening. At the same time, temperatures are rising dangerously. By Sunday, the thermometer in Piura could climb to 40 degrees.
Dramatic Days on the Border with Ecuador
The Zarumilla province in the far north of Peru was particularly hard hit. After heavy rainfall, the Río Zarumilla burst its banks. In Aguas Verdes and Puerto Perú, streets and residential areas were flooded. Affected families had to leave their homes while emergency responders helped with evacuations.
The situation also escalated in San Jacinto, in the Tumbes region. Several normally dry waterways suddenly carried large volumes of water. Streets were impassable at times, and individual towns were only partially accessible. For the residents, this meant not only flooded properties but also considerable difficulties in everyday life.
Río Tumbes: Fear of the Next Flood
The heavy rainfall also caused the Río Tumbes to swell. At times, the red warning threshold was exceeded. Authorities and emergency responders closely monitored the situation and prepared for possible further flooding.
Particularly dangerous are the so-called quebradas, normally dry waterways that can turn into raging torrents in a very short time during heavy rain. Further rainfall could endanger already affected residential areas again and disrupt additional road connections.
The Tumbes mangrove reserve is also located in the Zarumilla province. There, rainfall and water levels affect conditions in the water arms and mangrove channels. Visitors should inquire about the current situation before planning boat trips.
Piura: First a Rain Shock, Now Sweltering Heat
While Tumbes battles the masses of water, Piura faces the next weather extreme. Temperatures could already rise to 38 degrees on Thursday and Friday. For Sunday, even up to 40 degrees are predicted.
In addition, possible thunderstorms could bring heavy rainfall locally. Especially in areas with inadequate drainage, intense rain showers are enough to flood streets within a short time. The combination of extreme heat, high humidity, and possible heavy rainfall makes the weather situation particularly unpleasant.
Weather Outlook: How Things Will Continue Until Sunday
Predicted maximum temperatures in degrees Celsius:
| City | Thu. Nov 5 | Fri. Nov 6 | Sat. Nov 7 | Sun. Nov 8 |
|---|---|---|---|---|
| Piura | 38° | 38° | 38° | 40° |
| Tumbes | 29° | 28° | 30° | 31° |
| Chiclayo | 29° | 30° | 30° | 31° |
| Cajamarca | 22° | 21° | 21° | 22° |
Forecast status: November 5, 2026.
Thursday and Friday: New Thunderstorms Threaten
In Tumbes, the weather will initially remain unstable. Further showers and thunderstorms are possible, while temperatures will be between 28 and 29 degrees. In Piura, it will be significantly hotter, with temperatures of up to 38 degrees. Thunderstorms could develop there again, especially on Friday.
The weather situation will also remain changeable in the highlands. For Cajamarca, temperatures around 21 to 22 degrees and occasional rain are expected. Chiclayo, on the other hand, is likely to remain mostly cloudy and largely spared from heavier rainfall.
Saturday: No Relief in Sight
On Saturday, Tumbes will remain humid with around 30 degrees. Further thunderstorms are especially possible in the afternoon and evening. In Piura, the extreme heat will continue with temperatures around 38 degrees, while Chiclayo is likely to remain mostly dry at around 30 degrees.
For the areas already affected by flooding, the development is particularly critical. Additional rainfall could cause water levels to rise again and complicate cleanup efforts.
Sunday: 40-Degree Hammer for Piura
On Sunday, the heat in Piura could reach its preliminary peak. Up to 40 degrees are predicted. Temperatures in Tumbes and Chiclayo will also rise to around 31 degrees. While it remains oppressively hot on the coast, Cajamarca in the highlands will only reach around 22 degrees.
However, a complete weather calm is not guaranteed. Thunderstorms are possible again in Piura in the evening, while Tumbes must continue to expect isolated showers.
The Major Concern: What Happens During the Next Heavy Rain?
For the people in the affected areas, it is no longer just a question of whether it will rain again. Flooded streets, damaged transport links, and endangered homes clearly show what consequences intense rainfall can have within a short time.
Low-lying settlements and streets that pass through normally dry waterways are particularly problematic. There, new rainfall can become dangerous even if the weather situation in other parts of the region has already calmed down. The development of river levels therefore remains a crucial factor.
Sunday All Clear? Far From It!
Even if the rainfall could weaken locally towards the weekend, the situation in northern Peru remains tense. Tumbes must continue to expect rain and thunderstorms, while Piura suffers from exceptionally high temperatures. Furthermore, already flooded areas can still be affected by the consequences of the past rainfall for a longer time.
Northern Peru thus faces a weekend full of weather extremes. Whether the situation relaxes sustainably depends above all on how much rain actually falls in the coming days.
