Best Time to Dive
Predicting the best time to visit Bunder 1 often involves aligning with the drier season for optimal surface conditions. For excellent diving opportunities, aim for May, June, and October, when dive scores are consistently high (9 out of 10). During these months, average air temperatures hover around 28-29°C (82-84°F), contributing to comfortable surface intervals. Rainfall is significantly lower from May through October, often less than 6 mm (0.2 inches) monthly, drastically reducing freshwater runoff and improving visibility. Winds during these peak months tend to be milder, typically ranging from 19-21 km/h (12-13 mph), which usually results in calmer seas and less wave height, averaging below 0.5 meters (1.6 ft). Conversely, months like January and February experience higher rainfall, around 11-16 mm (0.4-0.6 inches), and stronger winds, potentially impacting the overall dive experience.
