Historical, current and forecast climate conditions around the country.

Climate Analysis
This interface allows users to view rainfall, maximum, minimum and mean temperature dekadal climatologies and seasonal anomalies.
This interface allows users to view rainfall, maximum, minimum and mean temperature monthly climatologies and seasonal anomalies.
This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal climatologies, anomalies and probability of exceedance.
This interface allows users to view rainfall, maximum, minimum and mean temperature seasonal trends expressed per year, over the selected period or percent of the average over the selected period.
This map shows the historical probability (given in percentile) of seasonal average monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry) one-third ("tercile") of the 1981-2016 historical distribution in the country given the state of ENSO (El Niño, Neutral, La Niña) during that same season.
This map shows the historical probability (given in percentile) of seasonal average monthly minimum or maximum temperature falling within the upper (hot), middle (normal), or bottom (cold) one-third ("tercile") of the 1961-2018 historical distribution in the country given the state of ENSO (El Niño, Neutral, La Niña) during the previous season (e.g. Jan-Mar temperature against Oct-Dec ENSO state).
This map shows the historical probability (given in percentile) of seasonal average monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry) one-third ("tercile") of the 1983-2015 historical distribution in Tanzania given the Terciles of IOD (Postive, Neutral, Negative) during that same season.

Climate Monitoring
This page displays dekadal (approximately 10-day) rainfall amounts over the country. The default map shows rainfall totals for the most recently available dekad, but totals for previous dekads can be displayed as well.
The Standardized Precipitation Index is an indicator of extreme rainfall events, whether they are drought or excess rainfall.
