our very latest forecasts for the sea surface temperature anomaly in the equatorial Pacific Ocean. The forecasts all indicate a sharp rise from the current neutral state to El Niño conditions (+0.5°C anomaly) by Summer this year. While there is still considerable uncertainty in the magnitude

extent of 18.53 million sq km was recorded on 30th August. Extent has fallen sharply since, reaching 17.85 million sq km by 10th October. From this time of year onwards Antarctic sea ice extent tends to fall rapidly as the sun rises towards its peak in the Southern Hemisphere, hence it is very likely

A deeper look at the meteorological drivers behind the change shows a strengthening jet stream, influenced by a sharp temperature gradient across North America, is helping to steer low pressure systems toward the UK. This will bring more unsettled weather through the Bank
