Growing: too cold
Planting: too cold
A week is in range when its average low and high sit inside the tolerance band 16 to 38 °C; it is suitable when that average range also overlaps the ideal 21 to 35 °C band and possible readings stay within 0 °C to 38 °C. Crossing a possible limit, or missing the ideal band, makes it tolerable; any chance of frost (possible low below 0 °C) makes it too cold. When a sowing window is calculated, weeks outside that window are uncoloured even if air is in range.
Based on average frost dates (35 seasons (1991–2025)).
