The 2024-2025 Hydrological Cycle Registers a Significant Excess of Precipitation

The State Meteorological Agency has revealed compelling data on current rainfall patterns, confirming that we are facing a hydrological period with exceptional characteristics in terms of recorded rainfall volume 🌧️.

Comparative Analysis of Rainfall Data

Between October 1, 2024 and September 2, 2025, 659 liters per square meter have been recorded, representing a 10% increase over the usual average values for this time interval. This upward trend had been manifesting since earlier, as by May 6, 2025, 570.2 l/m² had already been reached, approximately 20% above normal for those dates 📊.

Main Indicators of the Rainfall Surplus:
  • Total accumulation of 659 l/m² in the period October 2024 - September 2025
  • 10% increase compared to the historical average for the cycle
  • Early record of 570.2 l/m² by May, with a 20% excess
Nature seems determined to compensate for years of drought with an intensity that surpasses any artificial irrigation system

Contrast with the Previous Hydrological Cycle

The comparison with the preceding hydrological year is especially revealing. During 2024 (calendar year), precipitation reached 669.1 mm, equivalent to 105% of the normal value in the reference period 1991-2020. However, the current cycle has surpassed these figures with 683.7 l/m², representing an additional 7% over the reference average, confirming a continued upward trend in the rainfall regime 📈.

Interannual Evolution of Precipitation:
  • Year 2024: 669.1 mm (105% of normal value)
  • Current cycle 2024-2025: 683.7 l/m² (7% above average)
  • Notable accumulated surplus in the current period

Impact and Consequences of the Current Rainfall Regime

This sustained increase in precipitation carries multiple effects, from positive aquifer recharge to potential flood risks in vulnerable areas. The data reflects a clear positive deviation from climatic normality, possibly linked to changing atmospheric patterns or specific meteorological phenomena. Experts are closely monitoring this evolution, as such a rainy hydrological year can significantly influence both agriculture and hydrological planning in the medium term 💧.
