Solomon Islands Tropical Cyclone Outlook for 2026/2027 Cyclone Season.
Effective Date: 01st November 2026
Tropical Cyclone Outlook issued by the Solomon Islands Meteorological Services (SIMS) for the Solomon Islands region with associated preparedness advisories.
Summary statement
About 2 to 3 tropical cyclones (TCs) are expected during the current cyclone season from 01st November 2026 to 30th April 2027, which is also referred to as the wet season for the Solomon Islands region, inclusive of its Exclusive Economic Zone.

Climatology of Tropical Cyclones in the Solomon Islands.
Sea Surface Temperatures (SST) are currently warmer than average in the southwest Pacific, well above the +0.80 °C El Niño threshold. Based on the current the El Niño–Southern Oscillation (ENSO) analysis. The current El Niño event has firmly established, with further intensification into the New Year 2027. The El Niño event is now among the strongest levels in record. During an El Niño event, the South Pacific Convergence Zone (SPCZ) shifts northeast of its usual position. Both the ENSO and the Madden-Julian Oscillation (MJO), in combination with the SPCZ, play a significant role in TC development and intensity. El Niño events, generally bring “Below-normal” rainfall with prolonged dry periods for the Solomon Islands, causing very low monthly rainfall records. According to the latest rainfall outlook, “below-normal” rainfall conditions are expected in the upcoming season.
Recent Tropical Cyclone Season 2025/2026
During the recent cyclone season (2025/2026), 2 to 3 TCs were predicted for the Solomon Islands region. Three (3) TCs were developed in the vicinity of the Solomon Islands region with a couple of tropical low-pressure systems. On January 10th, 2026, a low formed south of Temotu Province moving southwest between Vanuatu and New Caledonia. Another low on 27th January 2026, south of Temotu and to east of Vanuatu and New Caledonia out from the tropics. SIMS issued strong wind warnings.
On March 17th, 2026, Tropical cyclone Narelle was formed 225nautical miles (NM) Southwest of Rennell Islands (northeast coral Seas) and tracked away from the Solomon Islands region. SIMS issued strong wind warning for all waters of Solomon Islands.
On April 03rd 2026, Special Weather Bulletin was issued for Western, Choiseul and Isabel provinces due to an intensifying tropical Low southwest of Western province.
At 23:00 hours, 5th of April 2026 (Late evening of Easter) Severe TC Maila was named and later intensified to category 5 in the Solomon Sea until it weakened to a tropical low again. SIMS issued Cyclone warnings for Western, Choiseul and Isabel provinces.
At the same period with TC Maila another tropical low-pressure system was located southeast of Temotu moving southward to become cyclone Vaianu between Fiji and eastern Vanuatu.
Disaster preparedness
It does not take a direct hit or severe TC to cause considerable damage or life-threatening weather. While Meteorological Drought Warning No.1 is being issued to all the provinces, it is also crucial for all stakeholder to stay prepared and vigilant for potential hazards such as:
- Tropical Low events
- Tropical Cyclone events
- Rainfall events
- Strong wind winds
- Dangerous marine conditions, including very rough seas, storm surges, and coastal flooding.
The TC induced rainfall may increase the risk of flash flooding in low-lying areas. Residents near rivers should be prepared to move to higher ground, while those living on or near hilltops should take precautions against potential landslides.
Residents around coastal areas should also take precautions against storm surges and high swells that could lead to coastal flooding.
Please stay tuned to SIBC, FM stations, and other media outlets for updates from SIMS and what to do information from the National Disaster Management Office and be sure to share this information with individuals with disabilities.
