Does Batumi get long rainy spells in summer or late August-September?

Recent reports describe summer 2026 in Batumi as rainier than usual: showers may occur almost every other day, but they generally start and end quickly rather than lasting all day.
No reliable long-range forecast really works — it's a subtropical climate where rain and sun can occur on the same day, so week-long weather forecasts usually don't hold true.
One traveler's experience suggests the truly reliable 'Batumi season' is essentially just the 30 days of August; other months, including autumn and spring, are much more unpredictable weather-wise.
Season = August (30 days)
Rain in Batumi is linked to the mountains: sea evaporation rises, cools near the mountains, and falls as precipitation, so areas near the hills (e.g. near the Alphabet Tower) are often cloudy. Despite this, during a trip from Aug 21 to Sep 3, there were few rainy days — just one downpour on the first day and one at night before departure.
Mountain rain mechanism; Aug 21–Sep 3 trip example
Late August and September can bring roughly two weeks of rainy days out of a month-long trip. Seas tend to be rough and the water colder, making swimming limited during these periods.
Late Aug–Sep: risk of prolonged rain
It really depends on luck — some years late August and September are rainy with poor swimming conditions, other years are fine.
In summer, rain in Batumi typically falls at night or before noon and rarely affects daytime activities.
Summer rain usually at night or morning
A full week of heavy rain in summer is theoretically possible in Batumi, though it's more the exception than the norm.
