How October compares

October is the 8th warmest month of the year in Kerala and ranks 29th of 134 destinations we compare for October - see where else is hot in October. Within India it is 2nd of 2 (India in October). Against London's average high of 14.6°C in October, Kerala is 13.6°C warmer by day and 15.7°C warmer at night.

Daytime and night-time in October

The typical October day in Kerala peaks at 28.2°C, but that is an average: the warmest 10% of days reach 29.3°C or more. About 100% of days top 25°C and 1 in 63 pass 30°C. Nights average 24.1°C; one night in ten drops to 23.6°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest October day here reached 31.1°C (2009-10-31) and the coldest night 21.7°C (1996-10-30).

Rain in October

Wet (more than 8 rainy days): about 26 days with 1 mm or more, 287 mm in total. Year to year it varies a lot - the wettest October was 2019 with 570 mm, the driest 2016 with 141 mm. Humidity averages 87%, which makes the heat feel heavier than the thermometer suggests.

Sea temperature in October

The sea averages 28.2°C - warm enough to swim (22°c+). Depending on the year it ranges from 27.6°C to 28.9°C. For the warmest sea here, come in April (29.9°C).

Sunshine and daylight

Around 2.1 hours of sunshine a day (estimated from cloud cover), 11.8 hours of daylight: the sun rises about 06:13 and sets about 18:08 local time in mid-October. Average cloud cover is 82%.

Is October a good time to visit Kerala?

It is a reasonable choice: hot days but expect showers. The best months for Kerala on our scoring are January, February, March; months averaging 25°C or more: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.

Warm days, sticky evenings

The heat is fairly steady rather than extreme: days reach 25°C throughout October, while only 2% reach 30°C. The bigger consideration is humidity at 87%, which can make walking around feel more tiring than the temperature alone suggests. Choose loose, breathable clothing and leave room for breaks rather than packing your days tightly. Midday is a sensible time to ease off if you find humid heat uncomfortable. With average night lows of 24°C, evenings offer limited relief, so do not expect the cool finish to the day you might get at home. Prioritise comfortable sleeping conditions when choosing accommodation.

Rain is the main compromise

With about 26 rainy days, wet weather needs to be part of the plan rather than treated as an occasional interruption. That does not establish how long rain will last on any particular day, so avoid assuming it will conveniently fall outside your outings. Sunshine averages just 2.1 hours within 11.8 hours of daylight: there is time to be out, but relatively little bright sun. Carry a compact umbrella or lightweight waterproof, choose footwear that tolerates getting wet, and keep weather-dependent plans movable. October is more suitable for travellers who can change their plans than for anyone relying on dry weather throughout.

Warm sea, but not a reliable sunshine holiday

At an average 28°C, the sea is warm enough for swimming without cold water being the main concern. Water temperature alone does not tell you about waves, currents or local swimming conditions, so follow advice where you are staying before getting in. The distinction matters in October: warm water and hot air do not add up to guaranteed beach weather when rain is so frequent and sunshine limited. Pack swimwear, but keep swimming as a flexible part of the trip rather than its sole purpose. This month makes more sense if warmth matters more to you than clear skies.
