People choose to come to Trimbakeshwar all your round to offer their prayers and seek blessings from Lord Shiva. However if you are planning a trip to Mumbai and then choose to go to Trimbakeshwar, then visiting the temple during the monsoon makes a lot of sense. This is because you will beat the heat and the climatic conditions are cooler. However it does get a little difficult to deal with the rains while travelling. This is why if you are not renting a cab then coming here during the monsoon may not seem like the best idea. Summers are best avoided because it's very hot and the temperatures can go up to 44 degrees Celsius. This will make it unbearable for you to travel.
