Weather in Maple Ridge in September

Prime time. September is about as good as Maple Ridge gets. Highs average 20.3 °C, lows 11.4 °C, and rain falls on 12 days — nothing in the month is working against you.

September ranks 4 of 12 in Maple Ridge: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 12 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest September day reached 36 °C and the coldest night fell to 3.5 °C, and the wettest single day dropped 46 mm — roughly 60% of the month's rain in one day.

September is moderately variable: 9 mm in the driest year against 160 mm in the wettest, around an average of 77 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 1.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 2.9 °C cooler than August, with October dropping another 5.7 °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 Maple Ridge's extremes of 16.2 and 8.2 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 22.9 °C between the year's warmest afternoons and coldest nights.

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 Maple Ridge versus nearby

If Maple Ridge is one option among several, the nearby comparison is worth making. Vancouver is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Nanaimo is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: September works, with August the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
