Montevideo: frost dates

Uruguay

Montevideo had no frost in 2016–2025, so crops are planted by warmth and rain rather than by frost dates.

Last spring frostnone in ten years
First autumn frostnone in ten years

Median of 2016–2025 for the 25 km grid cell of the city: the last day at or below 0 °C in spring and the first in autumn (ERA5 reanalysis via Open-Meteo). In a cold year a frost can come a week or two later — Greenly warns 48 hours ahead.

There is no frost season here: crops are planted by warmth and rain rather than by frost dates.
