Dekadal Agromet - October 2025 - 3rd Dekad

Rainfall and temperature review

Rainfall

The rainfall performance for third dekad of October 2025 shows a mixed pattern across the country (Fig 1), confirming a distinct spatial difference in recent moisture availability. Areas to the west (Leribe through to Mafeteng) and east (Mokhotlong) display near- normal to above -normal rainfall (Fig 1). Areas in the south (Mohale’s hoek and Quthing and north (Botha-Bothe) show negative (below normal) anomalies shown. This is evident from rainfall accumulation since the start of the season in August shown in Fig.2. For example, in the same period, Mokhotlong recorded 153,3mm against the long term of 120,7mm, while in the north Botha-Bothe observed 80,5mm compared to a normal of 130,5mm.

Although Dekad 3 of October in Fig.3 below shows a slight increase in rainfall compared to the other previous dekads (dekad 1 and 2), it still falls below the long term mean of the dekad.

Temperature

Maximum temperatures observed during the third dekad of October (Fig.4) were above the long-term normals (Fig.5) across the entire country. Fig. 4 shows most of the country experienced maximum temperatures exceeding 26.2⁰C in the southern and western lowlands, only the highest elevated areas specifically Sani-pass, recorded cooler maximum temperatures, falling within the 18.2⁰C to 22.2⁰C range.

Agricultural drought stress index

Water Satisfaction Index (WSI) for pasture tracks overall availability of water for plant growth throughout the seasons, Fig.6 shows a positive trend for the year 2025 up to November 1st. The cumulative WSI has reached a high of over 1000% (1053.78%) by beginning of November. This condition is highly favorable for livestock grazing and suggests a good foundation for crop growth in areas where planting is underway or planned.

The start (01st to 05th) of the dekad is likely to experience, dryer and warmer conditions with isolated rain and thundershowers. From the 06th Scattered to widespread rain and thundershowers are anticipated. Strong winds and hail can also be expected.

The bulk of Lesotho is likely to receive normal to above normal rainfall for the season, October to December (OND) 2025. For the following period, covering the rolling seasons from November-December-January (NDJ), December-January-February (DJF) 2025/26, to January-February-March (JFM) 2026, above-normal rainfall conditions are expected to dominate.

OND Season

This is a critical time for land preparation and sowing in all parts of the country. Given the above predictions, farmers are advised to start planting summer crops like maize, potatoes, sorghum, beans and horticultural crops; however, areas where flooding is experienced should be avoided, especially for planting crops like beans, potatoes andhorticultural crops. Farmers should seek guidance from Extension officers for their specific locations on proper sowing dates as well as good management practices.

Climate Smart Agriculture:

Farmers are advised to plant early maturing varieties, use protected structures especially for horticultural crops as temperatures are expected to be warmer. Irrigation schedules for horticultural crops are recommended to support crop growth and development. Livestock farmers are advised to keep animals under protected structures for protection against intense heat and other weather extremes.

Heavy rainfall

Heavy rainfall can cause waterlogging in seedbeds, nutrient leaching in prepared fields, and rapid surface runoff leading to soil erosion. Farmers should ensure that drainage systems are clear to prevent field water logging.

General Recommendations:

  • Regular consultations with Extension officers is highly recommended
  • Daily weather monitoring and use of indigenous weather forecasts is recommended for signs of significant rainfall patterns shifts.
  • Water storage during heavy rainfall can be beneficial for irrigation and drinking for animals.
