Taiga
Boreal forest, Alaska, U.S., dominated by spruce trees (Picea).
In the taiga, summer temperatures are generally cool to warm, supporting a short growing season characterized by long days.12
- Mean Temperatures: The mean temperature for July, typically the warmest month, generally ranges between 15 and 20 °C (59 and 68 °F).1
- Daytime Highs: For much of the growing season, daytime high temperatures are typically cool to warm, falling between 20 and 25 °C (68 and 77 °F).1
- Extreme Variations: If persistent high-pressure systems occur during the long days near the summer solstice, temperatures can occasionally warm to 30 °C (86 °F) or higher.1
These cool summer conditions are ecologically significant, as they can increase the photosynthetic efficiency of adapted plant species by reducing respiration rates, which allows for a greater net gain in biomass.1
