Review atmospheric patterns for a single representative coordinate over a thirty-year climatology period
These climate averages provide a standardized view of the environmental conditions at Lake Sumner Forest Park in Canterbury, NZ, based on NASA POWER data from 1991 to 2020. Measurements cover mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight hours for each month of the year. Please note that these figures reflect long-term trends at a specific point and do not account for microclimate variations or daily weather fluctuations within the broader park terrain.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
