Global surface anomaly down 0.165°C in April.

I've been waiting for three days for China to report - most others are very punctual lately. So it could change a little. But enough is enough - and last month, when I waited for China, they sent in February data, so it would have been better not to wait. Anyway, TempLS mesh showed a drop from 0.894°C in March to 0.729°C in April. That compares to a larger 0.226°C drop in the reanalysis index. Meanwhile, the troposphere indices went up - 0.08°C for UAH V6. As I often seem to have to say, it is a different place.

Despite the drop, April was still very warm. It was the 16th warmest month of any kind in the TempLS record. It was warmer than any annual average before 2016, including the then record year of 2015.

There was still quite a lot of warmth in the Siberia/Arctic region, and also in the east US. Antarctica was cold. Here is the breakdown plot:

Probably the main point of future interest is that SST is quite a lot higher. Elsewhere mostly moderate, which is a reduction for Siberia and Arctic.
