The month of June and July are the rainiest Monsoon months for the state of Kerala. The Monsoon rains start witnessing a reducing trend during the months of August and September. In fact, the sum up of the rains during June and July is more than double from the total rains the state records in August and September put together.
During the Southwest Monsoon season, the southernmost regions of the state which includes stations like Thiruvananthapuram and Punalur usually records least rains. On the other hand, the northern and central parts of the state, like Kochi, Kottayam, Kozhikode, and Kannur are used to getting comparatively good rains.
As per Skymet Weather, the early arrival of Southwest Monsoon over the region played wonders. This was the reason the overall rainfall performance of the state during the month of June ended on a surplus note. Spanning from June 1 to June 30, Kerala state as a whole was 15% rainfall surplus.

However, the reduction in the rains during the last couple of days in June and the first few initial days of July brought down the surplus status of the state into negative. Which is why the seasonal rainfall of the rains as on July 5 stood at -2%.
Though, Monsoon rains revived over the state in the last two to three days. In the wake of this, the state got to experience some good Monsoon showers once again. This is visible if take a look at the rainfall recorded by some of the stations of Kerala on the past day.

Within the span of 24 hours, from 08:30 am on Monday, Valparai recorded heavy rains to the tune of 83 mm, Kochi 82 mm, Alappuzha 79 mm, Kozhikode 36 mm, Punalur 28 mm, Karipur 22 mm, Thiruvananthapuram 18 mm, and Kannur recorded 10 mm of light rains.
According to Skymet Weather, the rainfall over Kerala generally picks up due to the activation of the offshore trough which runs along the West Coast. For the last couple of days, this trough was running from South Gujarat to Coastal Karnataka. As the system was north of Kerala, rains remained scanty.
However, now, the trough can be seen extending from Coastal Karnataka to Kerala coast and this helped in picking up the rainfall activity across the state. For the next two to three days also, Skymet Weather expects Monsoon rains of moderate to heavy intensity to continue.
Thereafter, these rains are likely to slow down once again around July 12 or 13 and the state can expect some light to moderate spells. The activity would pick up again henceforth under the influence of a cyclonic circulation likely to form in the Bay which would sustain its strength for a prolonged period and would prevail until July 17.
