Montevideo: frost dates

Uruguay

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.

A month before the first autumn frost, so the roots grow before winter.
