Weather in Tofino in September

A good month. September is a solid month to be in Tofino. Highs average 17 °C, lows 12.4 °C, and rain falls on 12 days — nothing in the month is working against you.

September ranks 3 of 12 in Tofino. Only July scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 12 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 17 °C days and 12.4 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 4.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 25.5 °C and the coldest night fell to 7.9 °C, and the wettest single day dropped 51 mm — roughly 49% of the month's rain in one day.

September is moderately variable: 14 mm in the driest year against 213 mm in the wettest, around an average of 104 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 6.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 87%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 1.6 °C cooler than August, with October dropping another 3.7 °C. The first week and the last are not the same trip. Rain is the thing that moves: October brings 6 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in September

12.7 hours of daylight, losing 1.8 hours across the month. That is between Tofino's extremes of 16.2 and 8.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 14.3 °C in September — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Tofino versus nearby

If Tofino is one option among several, the nearby comparison is worth making. Nanaimo is a better bet in September — 3.4 °C warmer, 2 days less rain. Vancouver is a better bet in September — 3 °C warmer, the same number of rain days.

So: September works, with July the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
