Weather in Jakarta

Weather - Jakarta

Jakarta has a true equatorial climate: temperatures change little through the year, humidity is high and the rain pattern defines the seasons. Expect daily highs around 30–33 °C and overnight lows near 22–24 °C, warm sea water (about 28–30 °C) and a pronounced wet season from roughly November to March. For travellers and flight shoppers, this means year‑round beachability but variable sightseeing conditions — pick June–September for the sunniest, driest stretch and November–March if you don’t mind frequent heavy showers (often short and intense).

Weather - Jakarta - January

January is one of the wettest months: daily highs around 30 °C, main temperatures near 23 °C and sea temperatures about 28 °C. Rain is frequent (around 17 days with some rain and high monthly totals), so expect heavy showers and cloudy spells interspersed with warm humid breaks — good for indoor museums or flexible sightseeing plans.

Weather - Jakarta - February

February remains hot and humid with daytime peaks near 31 °C and sea water around 28 °C. Rain days decline slightly (about 14 days), but humidity is very high, so bring lightweight, breathable clothing and plan activities around afternoon showers.

Weather - Jakarta - March

March still sits in the wet season: highs close to 32 °C and warm seas (≈29 °C). Rainfall is substantial with roughly half the month affected by showers, though sunshine increases compared with the heart of the wet season — expect sticky, tropical conditions ideal for short swims when the rain pauses.

Weather - Jakarta - April

April marks a gradual move toward drier weather: highs up to about 33 °C, main temperatures around 23 °C and sea temperatures near 29 °C. Rain frequency drops a little (around 15 rainy days) and daily sunshine increases, making it a decent shoulder‑season option for combining city sightseeing with beach time.

Weather - Jakarta - May

May is warm (daytime highs about 33 °C) with comfortably warm seas (≈30 °C). Rain becomes less dominant, and while showers still occur (roughly 14 days), you’ll notice more partly cloudy and sunny periods — a good month for outdoor activities before the driest months.

Weather - Jakarta - June

June is part of Jakarta’s drier season: highs near 32 °C, main temperatures around 23 °C and sea temperature about 29 °C. Rain is reduced (around 11 rainy days) and sunshine climbs, so this month is popular with travellers looking for more reliable beach and sightseeing weather.

Weather - Jakarta - July

July is typically one of the sunniest months with daytime peaks around 32 °C and fewer rainy days (about 9). Humidity remains noticeable but lower rainfall and more sunshine make July excellent for outdoor plans and exploring the city.

Weather - Jakarta - August

August offers warm, stable weather: highs near 33 °C, sea temperatures around 28 °C and only about 8 days with some rain. Sunshine is generally plentiful, making it one of the best months for beach trips and punctual travel itineraries.

Weather - Jakarta - September

September remains warm and relatively dry with daytime highs about 33 °C and the sea near 29 °C. Rain days stay low (around 8), while humidity is still present — a favourable month for combining city visits with coastal breaks.

Weather - Jakarta - October

October is a transitional month: highs around 33 °C and more frequent showers return (roughly 12 rainy days). Expect a mix of sunny stretches and heavier rain episodes — useful for lower‑price travel windows if you can tolerate some wet weather.

Weather - Jakarta - November

November moves firmly into the wet season again: daytime temperatures around 32 °C and sea water near 29 °C, with rain on many days (about 17). Heavy, brief downpours and increased cloudiness are common — plan indoor alternatives and expect higher humidity.

Weather - Jakarta - December

December is typically wet and humid with highs near 32 °C and roughly 18 days of rain. Sea temperatures remain warm (around 29 °C), so swimming is still comfortable, but sightseeing can be interrupted by frequent, intense showers.
