Conditions are warmest from December through March, with peak diving popularity running from late spring through autumn.

Water temperature stays warm year-round, with the coolest readings arriving in August before climbing again through the wet months. The best-months data points strongly toward late spring through autumn as the prime window, when conditions across both the main Padang Bai sites and the Candidasa sub-area are most reliable. Advanced sites such as Gili Biaha and The Toilet Bowl are particularly current-dependent, so timing a visit around settled conditions matters.
