Mexico received more rain in June than any other month on record, according to data from the National Meteorological Service (SMN).

The SMN, part of the National Water Commission (Conagua), reported that average accumulated rainfall across Mexico in June was 155.5 millimeters (6.12 inches).

That is the highest average national total for any month since Conagua began recording monthly rainfall totals in 1941. Last month superseded June of 2024 as the rainiest month on record in Mexico.

In contrast, June of 2023 was an extremely dry month, with an average accumulated national rainfall of just 39.2 millimeters, 60.7% below the average precipitation in the month of June between 1991 and 2020.

The national rainfall total in June this year was 55.7 millimeters, or 55.8%, higher than the average over that three-decade period.

Rain brought by Hurricane Erick, which made landfall in Oaxaca last month, and other storms, contributed to the high levels of precipitation in Mexico in June.

The day Erick made landfall — June 18 — was the rainiest day in Mexico in June.

The rain last month helped to replenish many of Mexico’s most important reservoirs.

Distributed generation is a step toward a clean-energy future, as it simply refers to electricity generated at or near the point of consumption. Solar panels are the most common form of such on-site energy production, and they are increasing in Mexico, with Jalisco leading the way.

The National Institute of Statistics and Geography (INEGI) reported over 5,000 more homicides in 2025 than the federal government, the largest gap in more than a decade. The discrepancy may partly lie with the state prosecutors’ offices that are supplying the government’s figures.
The Valle de Bravo reservoir in México state is at 99.14% of its capacity, holding 390.9 million cubic meters of water.
