Locust Watch

21/04/2026

Overview:

Climate models expect a rapid transition to El Niño conditions in the Pacific in the coming month, combined with a positive Indian Ocean Dipole. These signals are likely to generate wetter‑than‑normal conditions across all regions in May, followed by dry conditions in the southern parts of the Central and Eastern Regions. The summer breeding areas of the Western Region may receive above‑normal rainfall in northern areas, particularly toward the end of summer, while drier‑than‑normal conditions are forecast in the Central and Eastern Regions. Small‑scale spring breeding is still possible in Tunisia, Libya, Saudi Arabia, Yemen, Oman, Egypt, Sudan, Somalia, Iran, and Pakistan. Gregarious spring breeding is likely to continue in Morocco and may extend into Algeria. Summer breeding in the Sahel may occur, with an increasing risk of outbreaks toward the end of summer.

Key points:

  • Overview: The Desert Locust outbreak continued in Western Sahara and Morocco while spreading northwards.
  • Current situation: Adult groups moved northward in Western Sahara and Morocco, where breeding increased; hopper groups and bands appeared in Morocco; a few adult groups reached Algeria. Some locusts were also detected in the Canary Islands. No locusts were reported elsewhere.
  • Control operations: Decreased in March (25 137 ha treated) compared to February (34 564 ha).
  • Forecast: Adult groups and small swarms may continue moving northward into Morocco and Algeria, where increasing breeding may produce new hopper groups and small bands.

20/03/2026

Overview:

Climate models continue to indicate a rapid transition to El Niño in the Pacific by late spring, combined with a positive Indian Ocean Dipole. These signals are expected to generate wetter-than-normal conditions across all Regions during the spring. In summer, wet conditions may persist in the Western Region, while  drier-than-normal conditions are forecast for Eastern African, the Arabian Peninsula and the Eastern Region. Spring breeding is expected to remain small‑scale in Saudi Arabia, Yemen, Oman, Egypt, Sudan, Iran, and Pakistan. In the Western Region, gregarious spring breeding is likely in Morocco and may extend into Algeria, and potentially later into Tunisia and Libya. Summer breeding in the Sahel could begin earlier than usual, increasing the risk of outbreaks toward the end of the summer if predicted rainfall patterns materialize.

06/03/2026

Key points:

  • Overview: The serious Desert Locust outbreak continued in Western Sahara and southern Morocco.
  • Current situation: Adult groups increased and moved northward in Western Sahara and Morocco where breeding resumed; some adult groups reached the Canary Islands and Algeria. Some locusts were also detected in Mauritania, Egypt, Sudan and Eritrea. 
  • Control and operations:  Decreased in February (34 564 ha treated) compared to January (47 358 ha).
  • Forecasts: Adult groups and small swarms may continue moving northward into Morocco and Algeria where breeding may produce new hopper groups and small bands.

في شهر فبراير ، وتحديدا في المنطقة الغربية، استمر التفشي الخطير في الصحراء الغربية وجنوب المغرب. حيث ازداد عدد مجموعات الحشرات الكاملة غير الناضجة جنسيا في الصحراء الغربية، حيث نضج بعضها جنسيا وتكاثر وكانت بقع الحوريات لا تزال موجودة. كما ازداد عدد مجموعات الحشرات الكاملة الناضجة جنسيا وتحركت شمالا في المغرب، حيث تكاثرت في مواقع عديدة، ووصل بعضها إلى شمال أغادير. وصلت بعض مجموعات الحشرات الكاملة إلى جزر الكناري وغرب الجزائر. كما لوحظت الحشرات الكاملة المشتتة في وسط الجزائر. وقد تحركت مجموعات الحشرات الكاملة والأسراب الصغيرة خارج موريتانيا.
في المنطقة الوسطى، تم الابلاغ عن الحشرات الكاملة الإنعزالية والمشتتة في السودان، بينما وُجدت الحشرات الكاملة الإنعزالية فقط في مصر وإريتريا.  

22/02/2026

Overview:

Climate models continue to indicate a positive Indian Ocean Dipole and a rapid transition to El Niño in the Pacific over the coming months. These conditions are expected to increase rainfall across the Central and Eastern Regions during the spring. Tropical cyclones may develop over the Arabian Peninsula and will need to be closely monitored. Spring breeding in Saudi Arabia, Yemen, Oman, Egypt, Sudan, Somalia, Iran, and Pakistan is likely to begin on a small scale in March but may continue throughout the season. In the Western Region, models now forecast dry to normal conditions this spring across northwestern Africa. However, since gregarious breeding has resumed in Morocco, localized breedings are expected to persist through the end of winter and into spring, potentially extending into Algeria, Libya, and Tunisia.

إنقسام تفشي الجراد في المنطقة الغربية إلى قسمين
في شهر يناير، وتحديدا في المنطقة الغربية، انقسم تفشي الجراد الخطير في موريتانيا والصحراء الغربية إلى منطقتين. حيث استمر ​تواجد مجموعات الحشرات الكاملة غير الناضجة جنسيا وأسراب صغيرة في منطقة الإصابة الجنوبية الممتدة شمال السنغال وجنوب موريتانيا، والتي انخفض عددها خلال العقد الماضي. بينما امتدت منطقة الإصابة الأخرى من شمال موريتانيا إلى جنوب المغرب حيث تناقص عدد بقع ومجموعات الحوريات، بينما زادت مجموعات الحشرات الكاملة غير الناضجة جنسيا واستأنفت بعض مجموعات الحشرات الكاملة الناضجة جنسيا التكاثر خلال العقد الماضي. 
23/01/2026

Key points:

  • Overview: The serious outbreak in Mauritania and Western Sahara in Mauritania and Western Sahara split into two distinct areas in January.
  • Current situation: At the beginning of January, winds pushed groups and small swarms away from the Mauritanian coast, leading to the formation of two hotspots. In the south, between southern Mauritania and northern Senegal, several small immature swarms were observed. In the north, from northern Mauritania to southern Morocco, late‑instar hopper groups coexisted with immature, maturing, and locally mature adult groups. Adults were also reported in Egypt, Saudi Arabia, Sudan, and Yemen.
  • Control and surveys:  Survey and control operations must remain intensive from northern Senegal to southern Morocco, with additional surveys needed in Algeria. Monitoring should continue in the other countries.
  • Forecasts: Breeding may resume in Mauritania and extend into Senegal. Mature adult groups could also breed as far north as southern Morocco, leading to new hopper bands in February. Small‑scale breeding may also occur in the Central Region.

20/01/2026

Overview:

The establishment of a positive Indian Ocean Dipole circulation over the next two months, followed by the onset of El Niño in the Pacific in April, is becoming increasingly likely. Accordingly, seasonal models once again indicate a tendency toward wet conditions from Northwest Africa to the Middle East in February and continuing through May. Subseasonal models also forecast several rainy episodes over the next three weeks across various spring breeding areas. In the western region, a third generation of breeding could still occur north of the ongoing outbreak. The wet conditions expected in February could favour significant spring breeding in Morocco and Algeria, and possibly in Libya and Tunisia. In the central and eastern regions, above‑normal rainfall from February to June could support small‑scale spring breeding in Egypt, Sudan, Saudi Arabia, Yemen, Somalia, Oman, Iran, and Pakistan.

07/01/2026

Key points:

  • Overview: The Desert Locust outbreak remained serious in Mauritania and Western Sahara.
  • Current situation: Numerous adult groups and small swarms were present in Mauritania, while hopper groups and bands were fledging into adult groups and small swarms in Western Sahara. Adult groups spread from northern Senegal to near Tan-Tan in Morocco. Some locusts were also found in Algeria, Niger, Egypt, Saudi Arabia, Sudan and Yemen.
  • Control operations: Increased in December (81 654 ha treated) compared to November (33 273 ha).
  • Forecast: Breeding may resume in Mauritania and Western Sahara. Small swarms may migrate northward from Mauritania to Morocco. Some may reach Algeria and Senegal. Groups may appear in Sudan.

19/12/2025

Overview: 

Contrary to previous forecasts, seasonal models now indicate a trend toward drier conditions from northwestern Africa to the Middle East in January and February. However, subseasonal models predict rain events over the next four weeks across the three regions, and wet conditions could return in March and April in spring breeding areas. Depending on the development of El Niño conditions during spring, these wet conditions may persist, although confidence remains low at this stage. In the Western Region, as temperatures rise in January, a third generation of breeding could expand the ongoing outbreak. Wetter-than-average conditions may continue into spring breeding in northwestern Africa. In the Central and Eastern Regions, above-normal rainfall in March and April could support small-scale spring breeding in Egypt, Sudan, Saudi Arabia, Yemen, Somalia, Oman, Iran, and Pakistan.
