Weather & Crop Risk

• High
• Low
• Rain

GDD (base 10°C). Growing degree days accumulated over the 7-day forecast, base 10°C — a proxy for how fast crops will develop this week.

84 °C·d

Frost risk. Forecast days with a low at or below 0°C — cold-injury risk (냉해/서리) for seedlings, blossoms, and tender crops.

None

Heat stress. Forecast days with a high at or above 33°C — heat stress (폭염) that can scorch leaves and disrupt pollination.

None

7-day rain. Total rainfall over the past 7 days — context for waterlogging after 장마/집중호우 or a developing dry spell.

0 mm

Soil moisture proxy. Past 7-day water balance: rainfall minus reference evapotranspiration (ET₀). Positive trends wet, negative trends dry. A proxy, not a sensor reading.

Deficit (dry) · −25 mm

Why it matters: temperature and rainfall drive crop stage timing, frost and heat damage windows, and irrigation decisions — the difference between a saved harvest and a lost one.
