What's the weather like in Batumi the rest of the year

We've collected the weather data for Batumi during all other months of the year too:

Where does this data come from

Weather data for Batumi was collected from the MERRA-2 project from NASA, which used a climate model combined with historical data from weather stations around the world to estimate what the conditions were like for every point on the Earth.

For all data based on historical data, we've averaged the data from the past 11 years (2010-2020). For example, for the hourly temperature at 10am, we've looked at the temperature at 10am on every day in September (e.g., September 1, September 2, etc. in 2010, 2011, etc.) and took the arithmetic mean. We did not smooth the data, so for example, our daily temperature line will have some randomness due to the fact that weather is random in the first place.
