Rainfall data spanning a period of 50 years (1953-2002) for 9 stations in northern N igeria were used
to determine the trend in annual rainfall for the region. 5-year running mean was calculated for annual rainfall
for the selected stations. The decadal means were compared with the long-term mean. Evidence from the nine
stations considered shows that there is significant increase in annual rainfall amount in the last decade of the
study. It means, therefore, that we are experiencing wetter conditions in the sudano-sahelian zone of Nigeria.
Increasing annual rainfall totals portend both good and ill. Good, because there is improvement in water supply
to an otherwise marginal area. Ill, because flooding, dam collapse as a result of excessive rainfall on an
impervious terrain could lead to damage to life and property.
Key words: Rainfall, change, variability, agriculture, irrigation, running-mean,
