With a degree in Meteorology, I have a special interest in the weather. And, when it comes to the Bible, I pay particular interest to references to weather. In a few different instances, the writers of the Bible use the term "early and latter rains". Some examples include:

They do not say in their heart, β€œLet us now fear the Lord our God, who gives rain, both the former and the latter, in its season. He reserves for us the appointed weeks of the harvest.” - Jeremiah 5:24

Therefore be patient, brethren, until the coming of the Lord. See how the farmer waits for the precious fruit of the earth, waiting patiently for it until it receives the early and latter rain. - James 5:7

Contrary to popular belief, Israel actually receives a lot of rain every year. Admittedly, there are areas of the country where it is pretty dry (Jordan Rift Valley, Negeb, etc). But much of the land is very blessed by rain. 

The rain, however, falls in an interesting pattern. Every year, the rains start in late October and then continue until mid-May. This phenomenon is what the Biblical writers are referring to when they mention the early rains (October) and the latter rains (May). 

Since it is January, we are currently in the middle of the rainy season. The rains that fall right now help nourish the land for the rest of the year. Last week, Israel had an unusually rainy day. Many locations of the Galilee received nearly four inches of rain in one day. It was so much rain, that the water level of the Sea of Galilee rose three centimeters that same day. The Times of Israel had a very interesting story about it on their website.

Just as He did centuries ago, God is still ensuring that the land is properly watered.
