Climate bulletin - April 2013
Summary of the world's climate in April 2013.
The global average temperature in April 2013 was 0.43 ± 0.15 °C above the 1961-1990 average. Sea-surface temperatures in the tropical Pacific remained close to average, slightly lower than average in the east and slightly warmer than average in the west and central Pacific. Together with other atmospheric indicators, this is consistent with ongoing neutral El Niño Southern Oscillation conditions.
In April, land temperatures were below average across much of North America and Canada, Iceland, the UK and parts of eastern Asia. Much of Eurasia and north Africa was warmer than average as were large areas of Australia and New Zealand. Much of the observed surface ocean was warmer than average with areas of below average sea-surface temperature in the northern and eastern Pacific, south Atlantic and Indian Ocean. Sea-surface temperatures in the North Sea and Baltic were below average following the very cold weather in March and early April.
