Different parts of Rhode Island have different weather patterns that affect when frost happens. In Providence, plants can grow for 206 days, while in Burrillville, they only have 184 days to grow. This makes a big difference for people who garden or farm in these areas.
Big cities like Providence, Warwick, and Cranston have longer growing times. But places that are more inland or higher up, like Burrillville and Scituate, have shorter growing times. In these areas, the last spring frost might happen as late as May, and the first fall frost could come as early as October.
This guide helps gardeners and farmers by showing frost dates for different cities and towns in Rhode Island. It includes information about nearby weather stations and how far away they are, which helps people plan when to plant and harvest better.

First & Last Frost Dates of Rhode Island Cities and Towns
These Rhode island frost dates come from NCEI.gov’s weather records from 1991-2020. The dates shown have a 30% chance of frost happening.
When we talk about “First” and “Last” frost dates, remember these aren’t exact dates – they’re good guesses. The “Last Spring Frost Date” means it’s usually safe to plant after this date, but there’s still a small chance (30%) of frost coming later.
The “First Fall Frost Date” tells you when frost usually starts, but it might come a bit earlier (30% chance). Use these dates as helpful guides for your garden – they’re usually right, but not always!
