September 2020: Hottest September On Record Globally

September 2020 was the hottest September on record globally, according to the National Centers for Environmental Information, a division of the United States National Oceanic and Atmospheric Administration (NOAA).

Averaged as a whole, the global land and ocean surface temperature for this year’s September was 0.97°C above the 20th century average of 15.0°C. This value surpassed the previous record set in 2015 and, again in 2016, by only 0.02°C (0.04°F).

The ten warmest Septembers have occurred since 2005, while the seven warmest Septembers have occurred in the last seven years (2014–2020). September 2020 also marked the 44th consecutive September and the 429th consecutive month with temperatures, at least nominally, above the 20th-century average.

 South America and the Caribbean region had a January–September temperature departure that ranked as the second highest on record.

In Trinidad and Tobago, we also experienced record heat during September, with the highest temperatures recorded at both Piarco and Crown Point year-to-date.

At Piarco, August rainfall was much above average coming in at 297.7 millimeters (average is 188 mm) while at Crown Point, 109.3 millimeters were recorded.

Much of the Eastern Caribbean recorded a rainfall deficit for September 2020.
