Pre-peak sweet spot — dry season has arrived, visibility at 25–30m, and the crowds haven't caught up with the conditions yet.
#1 for good weather
Best match
Best dive conditions building to full peak — calm seas across all coasts, visibility 25–30m, manta and shark encounters reliable.
#2 for good weather
Best match
Post-European-summer crowd dip while conditions remain peak — this is arguably the best value month of the dry season.
#3 for good weather
Strong option
Dry season building — visibility improves week by week, manta rays still present, and Wayag lagoon open almost every day.
#4 for good weather
Strong option
European summer drives peak demand despite being the wet season on the calendar — prices hit their highest while conditions remain excellent.
#5 for good weather
Strong option
Absolute peak of the liveaboard season — every reputable operator running, best conditions of the year, highest prices of the year.
#6 for good weather
Strong option
Wet season returning — a transition month with good value, diving still excellent, but west-coast sites becoming unreliable.
#7 for good weather
Strong option
Transition month — rain is still heavy but calming seas make Wayag's karst lagoons accessible more days than January.
#8 for good weather
Strong option
Diving prime despite the rain — manta rays at Manta Sandy active all month, but west-coast sites rougher when westerly swells build.
#9 for good weather
Strong option
Still wet but the manta season peaks — Manta Ridge can see 15+ mantas in a single dive during February feeding aggregations.
#10 for good weather
Strong option
Christmas–New Year divers arrive for the manta peak — excellent diving despite heavy rain, but book liveaboards 3 months ahead for the holiday week.
#11 for good weather
Worth considering
Wet season in force — many operators close for maintenance, but manta season is beginning again and underwater visibility holds.
