The National Meteorology and Hydrology Service (Senamhi) reported on August 31, 2026, that daytime temperatures in Peru's rainforest, highlands, and coast will increase to extreme intensities through September 3. [^1]

Peru's Servicio Nacional de Meteorología e Hidrología (Senamhi) issued meteorological advisory No. 342 for an extreme daytime temperature increase, effective from 00:00 on September 1, 2026, to 23:59 on September 3, 2026, covering Lima, Callao, and 20 other regions. [^2]

The Instituto Geofísico del Perú (IGP) reported an earthquake with a magnitude of 5.2 at a depth of 42 km located 413 km south of Tacna, Tacna, on August 30, 2026. [^3]

In the northern and central rainforest, maximum temperatures are estimated to reach between 31°C and 38°C on September 1, with scarce cloud cover expected to increase UV radiation. [^4]

The National Civil Defense Institute (Indeci) recommended that the population apply sunscreen, wear wide-brimmed hats and UV-filtering glasses, and drink plenty of fluids to prevent heat-related issues. [^5]

For Lima and Callao, Senamhi predicts maximum temperatures of 24°C to 26°C on September 1, 2026, up to 28°C on September 2, and up to 29°C on September 3, 2026. [^6]

Senamhi forecasts maximum temperatures of 29°C to 36°C on the north coast, 24°C to 29°C on the central coast including Lima, up to 30°C on the south coast, and up to 32°C in the northern sierra during the advisory period. [^7]
