Typical Climate – Rhode Island
Köppen Dfa · ContinentalRhode Island has a continental climate (Köppen Dfa: Humid continental - hot summer), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 23.2°C, while January is the coldest at -0.4°C. Annual precipitation averages around 1297mm, spread fairly evenly across the year.
Monthly climate normals (2016–2025) - bar colour and height show average temperature, the shaded area shows average monthly rain, with snow (water-equivalent) shown separately.
Data: NOAA National Centers for Environmental Information (temperature/precipitation; frost: World Bank CCKP; snow: GPCC (DWD)).

Shifting Seasons
Warm / cold seasonsKöppen Dfb · ContinentalHow spring and autumn have shifted in Rhode Island. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (9.4°C, from 1950–1979); autumn is the date they fall back below it. Temperature swings 24.1°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Rhode Island changing?
Rhode Island is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
What is the climate like in Rhode Island?
Rhode Island has a continental climate (Köppen Dfa: Humid continental - hot summer), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 23.2°C, while January is the coldest at -0.4°C. Annual precipitation averages around 1297mm, spread fairly evenly across the year.
Where does the climate data for Rhode Island come from?
Climate data for Rhode Island comes from NOAA Climate at a Glance (temperature and precipitation), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Rhode Island climate data cover?
The Rhode Island climate profile covers Providence, Warwick, Cranston, Pawtucket and surrounding areas. Rhode Island climate data from NOAA Climate at a Glance
How often is the Rhode Island climate update refreshed?
The Rhode Island climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
What counts as a Heatwave Day on the Rhode Island climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the Rhode Island climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
