Weather in Funchal in August

Prime time. August is about as good as Funchal gets. Highs average 23.1 °C, lows 20.5 °C, and rain falls on 2 days — nothing in the month is working against you.

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

Rain falls on only 2 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average August reaches 30 °C; the day barely swings — 2.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest August day reached 26.6 °C and the coldest night fell to 18.5 °C.

August is moderately variable: 3 mm in the driest year against 20 mm in the wettest, around an average of 8 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind sits around 17.4 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How August sits in the year

Temperatures hold steady either side: 22.1 °C in July, 23.1 here, 22.8 in September. Nothing about the timing within the month matters much.

Daylight in August

13.4 hours of daylight, losing 0.9 hours across the month. That is between Funchal's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 23.3 °C in August — comfortable for a proper swim. This is the warmest the water gets all year.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May is the trade worth considering — 9 points weaker on weather, and materially quieter.

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

August in Funchal versus nearby

If Funchal is one option among several, the nearby comparison is worth making. Las Palmas de Gran Canaria is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Agadir is the weaker option in August — 15.3 °C warmer, 1 day less rain.

So: August is effectively as good as it gets here — 1 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
