Growing: tolerable
Planting: suitable
A week is in range when its average low and high sit inside the tolerance band 4 to 24 °C; it is suitable when that average range also overlaps the ideal 15 to 21 °C band and possible readings stay within 4 °C to 24 °C. Crossing a possible limit, or missing the ideal band, makes it tolerable; a possible low below 4 °C makes it tolerable. 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)).
