Tofo weather in May

Tofo forum threads describe January as genuinely hot, with late January into February marking the start of cyclone season locally - rain is a real feature of the month, though posters said it's typically quick, passing showers rather than sustained downpours, with year-to-year variation tied partly to El Niño patterns. On diving specifically, regulars were clear there isn't really a bad month at Tofo - January/summer is actually a better window for whale shark sightings, with giant manta rays present year-round regardless of season, making the rain a secondary consideration for anyone visiting primarily to dive.

Forum posters describe August as one of the coolest months at Tofo, both air and water - highs generally 24-27C - with a cold current pushing up from South Africa driving the chillier sea. Divers report a 5mm wetsuit is still manageable in July-August but genuinely chilly, and posters are consistent that June through September overall counts as a very good window to visit, with September specifically noted as a touch warmer than the peak of winter. Marine-life-wise, posters name Tofo's humpback whale season as running June through November, while giant manta ray sightings are described as a year-round draw regardless of the cooler winter water temperature.
