Weather Archive

The Weather Archive is a web application that allows you to browse and download historical weather data from weather stations across British Columbia. You can access monthly observation data in CSV format for analysis and research purposes.

Click on a weather station marker on the map, or select one from the "Weather Stations" list
The Observation Data panel will open on the right side
Select a year from the dropdown menu
Click the download icon next to the month you want to download
The CSV file will download to your computer

All weather observation data is provided in CSV (Comma-Separated Values) format. This format can be opened in spreadsheet applications like Microsoft Excel, Google Sheets, or imported into data analysis tools.

Click the "Weather Stations" button in the top-left corner of the map to open the station list. Use the search box at the top of the list to filter stations by name. You can also browse the map and click on any station marker directly.

The available years vary by weather station. When you select a station, the year dropdown will show only the years for which data is available for that specific station.

Manual Weather Stations

Field	Name/Definition	Notes	Units
CODE	Station Code
DATE TIME	Date and time of observation
OBS TYPE	Observation Type	Standard Observations are taken twice daily. In the morning between 0530-0730hrs and in the evening between 1530-1800hrs. Interval observations are made upon request if weather conditions warrant extra readings.
SKY COND	Sky Condition	CL = clear, OV = overcast, BR = broken, SC = scattered, OB = obscured, CL/H = clear/haze, SC/H = scattered/haze, BR/H = broken/haze
PRCP TYPE	Precipitation Type	NIL = none, * = snow, R = rain, */R = snow/rain, FR = freezing rain
PRCP RATE	Precipitation Rate	For Snow: VL = very light (<1 cm/hr), L = light (1 cm/hr), M = moderate (2 cm/hr), H = heavy (>3 cm/hr) For Rain: VL = very light (<1 mm/hr), L = light (1 mm/hr), M = moderate (2 mm/hr), H = heavy (>3 mm/hr)	Snow in cm, Rain in mm
MAX TEMP	Maximum temperature since the last standard observation		Degrees C
PRES TEMP	Present temperature at the time of the observation		Degrees C
MIN TEMP	Minimum temperature since the last standard observation		Degrees C
THERM TRND	Thermograph Trends	FR = Falling rapidly (>5 deg in last 3 hours), FS = Falling slowly (1-5 deg in last 3 hours), ST = Steady (<1 deg in last 3 hours), RS = Rising slowly (1-5 deg in last 3 hours), RR = Rising rapidly (>5 deg in last 3 hours)
RH	Relative Humidity		Percent
NEW SNOW	This is the accumulation of newly fallen snow since the last standard observation		cm
INT SNOW	Interval Snow - Amount of snow that has accumulated on the interval snow board		cm
STORM SNOW	Storm Snow - The amount (rounded cm) of snow since the beginning of a snow storm that has accumulated on a storm snow board		cm
STORM CLEARED	Flag indicating that the Storm Board was cleared. This indicates that the observer felt that the storm was over.
SNOW PACK	This is the current depth of snow		cm
SURF COND	Surface Condition	SH = surface hoar, IC = ice crust, WE = wind effect, New = new, Oth = other, Old = old, Sl = slush
PRCP GAUGE	Precipitation Gauge - The current total depth of water contained in a precipitation gauge, irrespective of the form of the precipitation		mm
OLD GAUGE	Old Gauge - Precipitation total as read from previous "Precipitation Gauge Total" reading		mm
NEW PRCP	New Precipitation - The total precipitation, irrespective of form, to fall since the last standard observation (in mm). This is the difference between the current Precipitation Gauge Total and the Precipitation Gauge Total at the last standard observation (Precipitation Gauge Total Old). Minus sign is included if it is a negative value.		mm
