This page presents Madagascar's projected climate. Data is shown as either the projected mean or anomaly (change) and is presented spatially, as a seasonal cycle, time series, or heatplot, which shows seasonal change over long-term time horizons. We offer a range of variables at both national and sub-national aggregations. Data can be analyzed as annual or seasonal; monthly data is available in the Data Download page. You can further tailor your analysis by selecting different projected climatologies and emission scenarios, or Shared Socioeconomic Pathways (SSPs). On this page, projection data is presented as multi-model ensembles, which represent the range and distribution of the most plausible projected outcomes of change in the climate system for a selected SSP. It is important to note that SSPs are meant to provide insight into future climates based on defined emissions, mitigation efforts, and development paths.
Climate projection data is modeled data from the global climate model compilations of the Coupled Model Inter-comparison Projects (CMIPs), overseen by the World Climate Research Program. Data presented is CMIP6, derived from the Sixth phase of the CMIPs. The CMIPs form the data foundation of the IPCC Assessment Reports. CMIP6 supports the IPCC's Sixth Assessment Report. Projection data is presented at a 1.0º x 1.0º (100km x 100km) resolution.
This page provides a generalist overview, offering a selection of the most popular indicators, presented through multi-model ensembles. An expanded suite of indicators that can be investigated as either multi-model ensembles or individual models is available through our Mean Projections (CMIP6) - Expert Page. Data from the CMIP5 Collection can still be accessed by the link below.
- By 2065, temperatures are projected to increase between 1.1°C and 2.6°C, with the lowest projected increases along the northern coastal regions and the highest projected increases for the southern part of the country.
- By 2065, in the southern part of the country rainfall is projected to increase during the summer months of January-April, and again in October- November, with the exception of the southernmost station, which may become drier in October; and to decrease during May, with greater decreases projected inland through June and July and additional during August and September.
- By 2065, projected changes in rainfall are less certain for the north, with some models suggesting drier and others suggesting wetter conditions.
