Climate of Temperate Forests: Temperature, Rainfall & Seasons

Temperate forests occupy mid-latitudes (~30°–50° N/S) with distinct seasons and moderate climates. Here's the typical climate profile:

Temperature

• Annual Average: 5–15°C (41–59°F).
• Summer Highs: 20–25°C (68–77°F).
• Winter Lows: -5–0°C (23–32°F) — below freezing common.
• Range: Continental interiors: larger extremes; coastal: moderated.

Precipitation

• Annual: 750–1,500 mm (30–59 in).
• Distribution: Fairly even year-round; summer convective storms, winter frontal/cyclonic.
• Form: Rain in warm months; snow in winter (persistent snowpack in higher/colder zones).

Humidity & Light

• Humidity: 60–80% average; high near canopy/streams.
• Sunlight: Strong seasonal variation. Long summer days (high photosynthesis); short winter days (dormancy).

Seasonality

• Spring: Budburst, wildflower bloom, snowmelt pulse.
• Summer: Full canopy, peak growth, thunderstorms.
• Autumn: Senescence, leaf color, abscission, seed dispersal.
• Winter: Dormancy, snow cover, subnivean activity.

Subtypes

• Deciduous: Broadleaf (oak, maple, beech) — E. US, Europe, E. Asia.
• Coniferous: Needleleaf (pine, spruce, fir) — boreal transition, mountains.
• Mixed: Both.
• Mediterranean: Winter rain, summer drought (chaparral/maquis).

This climate supports high productivity, deep soils, and immense biodiversity.
