Currently in Boston — October 3, 2023: Summer warmth for a few days
Plus, El Niño continues to accelerate global temperatures.

The weather, currently.
Warm and sunny
Sunny days and clear nights are in the forecast through Thursday. It will be summer-like tomorrow with readings in the lower 80s away from the beaches. More warm weather continues Wednesday and Thursday with highs 75-80 each day. There could be some ground fog to start the mornings with readings withing a few degrees of 50. Clouds arrive Friday ahead of a cold front. Saturday, like so many others this summer and fall, brings a few showers but we should clear for Sunday and Monday. Temperatures will be cooler over the weekend generally in the 60s, but perhaps only near 60 on Monday as Canadian air arrives.
What you need to know, currently.
New data show that the last week of September was the most anomalously warm week in history. That’s not so surprising given that we’re going into what looks like a very strong El Niño — the tropical Pacific warmth that defines these linked ocean-atmosphere patterns typically starts spreading worldwide during the last four months of the year.
Here’s more, from CarbonBrief:
Global surface temperatures set a new record this week for the highest daily temperature anomalies (departure from the norm) ever observed. They were recorded by a Japanese climate database called the JRA-55 reanalysis product. These were approximately 1C warmer than the 1991-2020 baseline period used by the dataset and around 1.9C warmer than the pre-industrial (1850-1900) temperatures.
As Currently reported last week, these data add to the increasing likelihood that we may already be living in the first 12-month period that’s 1.5°C warmer than pre-industrial levels, and that a few upcoming weeks may top 2°C for the first time ever.
