APEC Climate Center

APCC partnered with Seoul National University and the Secretariat of the Pacific Regional Environment Programme (SPREP) to host a regional training workshop in Nadi, Fiji, from April 20 to 22, 2026. The event brought together around 40 participants, including climate prediction officers from the meteorological agencies of 14 Pacific Island nations, as well as key stakeholders from climate-sensitive sectors like water resources and agriculture.

APCC's outlook for for May - October 2026 is live on our website! Check out our outlook here: https://www.apcc21.org/prediction/global/outlook?lang=en

* The APCC ENSO Alert suggests “El Nino WATCH”. El Nino is expected to develop in the coming seasons.

* Above normal temperatures is mostly probable for the most of the globe except for northern Australia and adjacent regions.

* Above normal precipitation is predicted for the tropical North Pacific and eastern end of equatorial Pacific. Below normal precipitation is predicted for the Maritime continents, off-equatorial south Pacific for May— July. During August — October 2026, above normal precipitation is expected for the equatorial Pacific. Below normal precipitation is expected for the Maritime Continents, Indian subcontinent, subtropical Indian Ocean, the Caribbean, the Central America, and northern part of the South America.

APCC's outlook for December 2024 - May 2025 is live on our website! Check out our outlook here: https://apcc21.org/prediction/global/outlook?lang=en
* The APCC ENSO Alert suggests “La Niña Watch”. Niño3.4 index is expected to be -0.8℃ for January 2025 and gradually increase to -0.3℃ for May 2025. La Niña conditions are most probable (62%) for December 2024 — February 2025, with a shift to ENSO-neutral conditions expected to be more probable (57%) from February — April 2025 and March — May 2025.
* Strongly enhanced probability for above normal temperatures is predicted for most of the globe except for the central and eastern tropical Pacific for December 2024 — May 2025.
* For the same period, strongly enhanced probability for below normal precipitation is predicted for the western equatorial Pacific.

Due to its unique geographical characteristics, the Pacific Islands have significant yet untapped potential for climate prediction. Large-scale climate variability, such as ENSO (El Niño-Southern Oscillation), significantly impacts year-to-year climate variability in these islands, though the local manifestations of such large-scale changes can vary by time and location.

The APEC Climate Center (APCC), a technical partner of UNEP CISPac-5, has developed a climate prediction tool called PICA*O (Pacific Island Countries Advanced Seasonal Outlook). PICA*O provides locally tailored, improved climate predictions for 14 Pacific Island countries.

As part of the UNEP CISPac-5 activities and with support from the ClimSA project, APCC held a regional training workshop on climate prediction and the use of PICA*O.

This workshop came to an end on 18 Oct. in Nuku'alofa, Tonga and aims to enhance the capacity of NMHSs to produce high-quality in-house seasonal forecasts and to improve understanding of climate prediction techniques and the theoretical background of climate variability.

APEC기후센터 신도식 원장, '아동학대 예방 릴레이 캠페인' 동참
안녕하세요. APEC기후센터입니다.
# APEC기후센터는
아동학대 예방 및 아동을 하나로 독립된 인격체로 존중하는 긍정양육 문화 확산하는 '아동학대 예방 릴레이 캠페인'에 참여하게 되었습니다.
🔎 '아동학대 예방 릴레이 캠페인'이란?
2024년 5월부터 시행된 보건복지부·아동권리보장원 주관의 캠페인으로, 아동학대 예방과 건강한 성장 환경을 마련하자는 취지로 긍정양육 메시지를 SNS에 게시하고, 실천 주자가 둘 이상의 개인 또는 기관을 지명하는 방식으로 챌린지를 지속하는 캠페인입니다!
신도식 원장님은 #한국청소년상담복지개발원 윤효식 이사장님의 지목을 받아
이번 캠페인에 참여하게 됐습니다^^
