Climate Data

Climate change will present a variety of risks and opportunities in Newfoundland and Labrador. Having access to up-to-date and relevant climate data is important for decision-making processes in areas as diverse as infrastructure planning, economic development, business investment decisions and preparing for risks to public health. This page brings together a significant amount of climate data and tools that have been developed for Newfoundland and Labrador over the last number of years.

Climate Data Information Portal External Link
The Climate Information Portal is a section of the Provincial Government’s Community Accounts database that includes historical climate data from over 70 Environment Canada weather stations throughout Newfoundland and Labrador, including temperature, wind and precipitation data from as early as 1909.

Road Weather Information System Data
By using the Community Accounts website, individuals can access temperature, wind and gust data from 2006 to 2014 across 32 monitoring stations. Daily data is available for stations across Newfoundland and Labrador. The RWIS data can be viewed on the Community Accounts website at:

Intensity-Duration Frequency (IDF)Curves PDF
IDF curves identify the intensity of rainfall events (in millimeters per hour) over a specific duration (ranging from five minutes to 24 hours) and how frequent these rain events are expected to occur (ranging from a one-in-two to a one-in-100 year event). These tools inform the appropriate design standards and management practices for infrastructure. The Provincial Government has compiled and updated IDF curves for 19 locations in the province and developed projections of future extreme precipitation events.

Temperature Projections Excel
In 2013, the Provincial Government commissioned a Climate Projections Study that identifies how the province’s climate is projected to change by mid-century. This study includes temperature projections for 16 locations in the province. Specifically, daily mean, minimum and maximum temperatures are available for all seasons, and projections are available for technical concepts, such as heating degree days, cooling degree days, growing degree days, frost days and heat waves.

Precipitation Projections Excel
The Provincial Government’s 2013 Climate Projections Study, which outlines how the province’s climate is expected to change by mid-century, provides precipitation projections for 16 sites in the province. Specifically, daily mean precipitation, daily precipitation intensity, and precipitation totals for three, five and ten-day periods are provided for all seasons, as well as projections for dry spells.

Flood Alert System Updates
A flood alert was launched by the Provincial Government to help communities prepare for storms, which can help them avoid future high-cost repairs and improve emergency response planning. This system provides daily alerts and forecasts for 45 areas from July to December each year, including projected daily rainfall, flood risk levels, and the time of estimated peak precipitation for that day.

Additional Tools and Resources:

  • Climate Monitoring Report PDF - This study, which was completed in 2012, provided an inventory of climate monitoring capabilities in Newfoundland and Labrador, including which climate stations have been maintained or discontinued, and the type of data being collected.
  • Climate Projections Study PDF - In 2013, the Provincial Government commissioned a Climate Projections Study that identifies how the province’s climate is projected to change by mid-century. As noted above, this study provides temperature and precipitation projections
  • Flood Risk Mapping Studies - Flood risk maps are available for 40 locations in Newfoundland and Labrador. These maps show which areas covered by the maps are prone to over-land flooding, with the most recent maps indicating how flood risk areas will change as a result of climate change.
  • Coastal Erosion Monitoring PDF - Since 2011, the Provincial Government has been monitoring coastal erosion rates throughout the province, with 120 sites currently being monitored. Reports of the findings of this work are released annually. The Geoscience Atlas provides detail on each of these sites.
  • Public Infrastructure Engineering Vulnerability Committee Workshops - In 2014, the Provincial Government hosted a series of workshops attended by over 120 engineers, municipal staff and decision-makers to apply a vulnerability assessment tool to three infrastructure scenarios in Newfoundland and Labrador. The following case studies were produced:
