ORLANDO, Fla. – With Florida facing its worst drought in 25 years, an early start to the rainy season would be a big help. But with daily rain chances back in the forecast for this upcoming week, many Central Floridians might start wondering could this be the kick start to an early wet season?
In Central Florida, the rainy season doesn’t have one official “start date” the way hurricane season does, but there is a clear pattern shift to watch for.
One important thing to remember about the start of Central Florida’s wet season is that we don’t know the official start date in real-time. It’s determined after the fact, using rainfall patterns over several weeks. So even though we’re currently seeing a stretch of daily rain, a single rainy week doesn’t automatically mean the wet season has officially begun.
When does “wet season” typically begin?
Most years, that transition from dry to wet comes in late May when humidity climbs and our daily sea breezes return, which helps fuel rain and thunderstorms almost every afternoon.
In Orlando and Sanford, the rainy season tends to begin around May 27, while nearby cities like Daytona Beach and Melbourne usually see it start within a few days of that.
The timing can vary quite a bit from year to year. Some seasons start as early as the first week of May, while others have waited until June or even early July to settle in. This wide range shows just how much the atmosphere can influence when our wet patterns really take hold.
What is the criteria for the ‘wet season’?
It is dependent on three main factors:
- Increased humidity levels
- Warm temperatures in the day and at night
- Daily showers and thunderstorms
Once these conditions become the daily pattern for a few weeks, we generally consider the rainy season underway.
How long does the ‘wet season’ last?
On average, the rainy season in Central Florida lasts about five months, typically stretching from late May through mid-October, and accounts for a significant portion of Central Florida’s total annual rainfall.
The yearly shift into this wetter pattern is important because it marks the end of Florida’s relatively dry months and ushers in nearly daily afternoon showers and storms that give the Sunshine State its reputation for unpredictable but regular summer rain.
