October 2020 was the 4th 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 October was 0.85°C above the 20th century average of 14.0°C. Only Octobers of 2015 (+1.03°C), 2019 (+0.95°C), and 2018 (+0.93°C) were warmer.
The ten warmest Octobers have occurred since 2005, while the seven highest October temperature departures from average have occurred in the last seven years (2014–2020). October 2020 also marks the 44th consecutive October and the 430th consecutive month with temperatures, at least nominally, above the 20th-century average.
The Northern Hemisphere land and ocean surface October 2020 temperature was also the fourth highest on record, while the Southern Hemisphere had its ninth-warmest October in the 141-year record.
The first 10 months of the year were warmer than average across much of the globe. Record warm January-October temperature departures were widespread across northern and southeastern Asia and across parts of Central and South America, Europe, the Indian, Atlantic and the western and northern Pacific oceans. According to a statistical analysis done by NCEI scientists, the year 2020 is very likely to rank among the three warmest years on record.
The Caribbean, as a whole, temperature departure ranked among the 10th highest for October on record. South America and the Caribbean region had their second warmest January–October period.
In Trinidad and Tobago, we also experienced record heat during October, with the highest temperatures recorded at Piarco year-to-date.
At Piarco, October rainfall was much above average coming in at 285.3 millimeters (average is 207 mm) while at Crown Point, 197.1 millimeters were recorded.
Much of the Eastern Caribbean recorded a rainfall surplus for October 2020.
