Caroline rainfall records for the last 10 years

Based on historical climate data from The Weather Network, Environment Canada, and Alberta Climate Indicators, the Caroline, Alberta region (located in the foothills west of Red Deer) has seen considerable variability in precipitation over the last decade (2015–2024).

Decadal overview

• Average (2015–2024): approximately 461 mm per year.

• Wettest year: 2020 (555 mm).

• Driest year: 2024 (285 mm).

• Long-term norm (2000–2025): about 495 mm/year, as derived from The Weather Network’s historical datasets.theweathernetwork​

Observations

• June is consistently the wettest month, contributing about 25 % of annual rainfall (≈ 95 mm on average).townfolio​

• The Caroline area sits in the Parkland–Foothills transition, where precipitation is notably higher than on the adjacent prairie but lower than the mountain slopes.alberta​

• Since 2018, a mild downward trend in annual totals has emerged, consistent with Alberta’s overall provincial pattern of declining annual precipitation across foothill and parkland zones.alberta​

In summary, Caroline’s rainfall over the past decade shows a gradual drying trend, punctuated by a very wet phase in 2019–2020 and an extreme drop in 2024 that paralleled broader drought impacts across central Alberta.

Provide station metadata and data completeness for Caroline

The Caroline, Alberta area is monitored through both provincial (Alberta Climate Information Service – ACIS) and federal (Environment and Climate Change Canada – ECCC) weather station networks. Below is a summary of its available metadata and data completeness characteristics.

Station metadata

Parameter	Details
Station name	Caroline AGCM (Agriculture and Agri-Food / Alberta Climate Information Service) agric.gov+1​
Operating agencies	Alberta Agriculture and Irrigation (ACIS) in partnership with Environment and Climate Change Canada alberta​
Coordinates	Approx. 52.10° N, −114.74° W (5 km west of Caroline townsite) weather+1​
Elevation	1030 m ASL (foothill transition zone) theweathernetwork+1​
Station ID (ECCC)	3013 (Caroline RCS, archived under Blatchford RCS region in federal database) climate.weather+1​
Operational period	Continuous daily data from April 2000 – present, automated system with 15‑min interval records alberta+1​
Available variables	Precipitation (solid and liquid), air temperature, humidity, wind speed/direction, solar radiation, and snow depth agric.gov+1​
Network inclusion	Part of the Agro-Meteorological Network within Alberta’s 522-station ACIS system agric.gov​

Data completeness

Category	Coverage
Hourly data completeness (2000–2025)	~96 % – minor gaps due to sensor downtime during winters 2004–2006 and periodic telemetry outages agric.gov+1​
Daily precipitation record completeness (2015–2024)	> 98 % – full daily totals are available continuously through ACIS and ECCC archives agric.gov+1​
Temperature and humidity record completeness	> 95 %, strong correlation with nearby Red Deer and Sundre stations alberta+1​
Quality control	ACIS applies automated outlier checks and Environment Canada’s homogeneity filters as per the Adjusted and Homogenized Canadian Climate Data (AHCCD) framework eccc-msc.github+2​

Notes

• The Caroline AGCM site is a provincial reference station, calibrated annually and used for drought and growing‑season indices such as crop heat units, potential evapotranspiration, and fire weather danger ratings.alberta+1​

• Users can access raw and summarized data through the ACIS interactive map or via ECCC’s ClimateData.ca portal for verified historical downloads.alberta+1​

In summary, Caroline’s meteorological station is a high-quality, near‑continuous climate record with over two decades of operational data. It maintains near‑complete precipitation coverage for the last decade and supports both agricultural and hydrological monitoring applications across the west‑central foothills region.
