Another record month, in a year that will almost certainly be the warmest on record. Note also that no month in any year in history has had a temperature higher than the then-average for the month than September 2015's 0.90 degrees C above the historical September average.
And of course, the temperature for all of 2015 is going to set a record.
Oh, and if you're going to claim that it's just a strong El Nino that's responsible:
Edit: Unsurprisingly, climate-denial-central (aka WattsUpWithThat.com) continues its valiant fight to understate what's happening with the Earth's temperature, and informs us that
The combined average temperature over global land and ocean surfaces for September 2015 was the highest for September in the 136-year period of record, at 0.90°C (1.62°F) above the 20th century average of 15.0°C (59.0°F), surpassing the previous record set last year in 2014 by 0.12°C (0.19°F). This marks the fifth consecutive month a monthly high temperature record has been set and is the highest departure from average for any month among all 1629 months in the record that began in January 1880. The September temperature is currently increasing at an average rate of 0.06°C (0.11°F) per decade.
Separately, the September average temperature across global land surfaces was 1.16°C (2.09°F) above the 20th century average, also the highest for September on record. Large regions of Earth's land surfaces were much warmer than average, according to the Land & Ocean Temperature Percentiles map above. Record warmth was observed across northeastern Africa stretching into the Middle East, part of southeastern Asia, most of the northern half of South America, and parts of central and eastern North America. Southern South America, far western Canada, Alaska, and a swath across central Asia were cooler or much cooler than average.
And of course, the temperature for all of 2015 is going to set a record.
The first nine months of 2015 comprised the warmest such period on record across the world's land and ocean surfaces, at 0.85°C (1.53°F) above the 20th century average, surpassing the previous records of 2010 and 2014 by 0.12°C (0.21°F). Seven months this year, including the past five, have been record warm for their respective months. January was the second warmest January on record and April third warmest.
The average global sea surface temperature of +0.69°C (+1.24°F) for the year-to-date was the highest for January–September in the 136-year period of record, surpassing the previous record of 2014 by 0.06°C (0.11°F). The average land surface temperature departure from average of +1.28°C (+2.30°F) was also the highest on record for September, surpassing the previous record of 2007 by 0.16°C (0.29°F).
Oh, and if you're going to claim that it's just a strong El Nino that's responsible:
With strong El Niño conditions in place, the September global sea surface temperature was 0.81°C (1.46°F) above the 20th century average of 16.2°C (61.1°F), the highest departure for September on record, beating the previous record set last year by 0.07°C (0.13°F). This departure from average is also 0.25°C (0.45°F) higher than the global ocean temperature for September 1997, when the last strong El Niño occurred.

Globally it was the fifth warmest September in the satellite record.
