エルサレムの月別の天気

Located near the eastern edge of the Mediterranean Sea, Jerusalem has a Mediterranean climate with hot, dry summers and cool, wet winters. Due to its relatively high elevation (600 m-800 m above sea level) Jerusalem's air is less humid and more pleasant than in most other parts of Israel. Winters are often wet, with nearly all of Jerusalem's annual 590 mm (23 in) of precipitation occurring between October and April. However, in between the rainy days there are numerous clear and sunny days. The coldest month is January, with an average high of 12 °C (53 °F) and an average low of 4 °C (39 °F). Sub-freezing temperatures are rare, but do happen, and the city will get occasional snowfall during the winter, though it usually only lasts a matter of hours rather than days. Once every few years, the city will experience significant accumulating snow. Summers are hot and dry as a bone with virtually no rainfall between the months of May and September.…

Jerusalem forum threads describe January as genuine winter here, with typical highs around 10-15C and real potential for heavier rain spells, though posters were consistent that any given wet stretch rarely lasts more than a couple of days before clearing. Snow is a real possibility given Jerusalem's elevation but stays rare in practice - maybe once every couple of years rather than an annual event. The consistent packing advice: layers you can add and remove through the day, since a sunny moment can feel genuinely warm while stepping into shade brings a noticeably cold breeze - the swing between sun and shade was repeatedly flagged as more dramatic here than visitors expect.

Jerusalem forum regulars describe April as the reward for skipping winter and beating summer: warm but not very hot, with rain unlikely, mornings “probably in the 50s” and days “probably 69s-72” — evenings cool enough that a light jacket or sweater stays useful even on a warm day. The one wrinkle to plan around isn't weather at all: Passover crowds mean tourist sites get busy and hotels pricier for that week, with regulars recommending arrival after the holiday rather than during it. Our record backs the mild, dry read: 22.5°C days, 10°C nights and just 3.4 rain days for the whole month.

A Jerusalem-forum thread on May evenings gets specific about the city's one weather quirk: the elevation. Days run warm and reliably sunny with precipitation 'very unlikely' by this point in spring, but posters are consistent that evenings cool off more than visitors expect, enough that a jacket or sweater earns its space in the bag even after a warm afternoon. The record confirms both halves: 27.5C days feeling like 28C, 16.8C nights, just 2.2 precipitation days and 12.6 hours of sun - one of the driest, sunniest stretches on the calendar, with humidity a low 50 percent that keeps the heat from feeling heavier than it is.

At 800 metres the heat here is dry rather than oppressive, and regulars call June bearable compared with what August brings. Our row backs the dryness precisely - 29.8C reading as 31C at 52.8 percent humidity, roughly half the humidity a coastal city would carry at the same temperature - and the evening cool they describe: one visitor put on long sleeves for dinner after finding the evening surprisingly cool for what had been a hot day. Our night reads 19.1C, warmer than their impression, though the swing from a 30C afternoon still catches people out. Rain has essentially stopped, 2mm across less than a day. The record: a dew point of 10.3C, 13 hours of sun, a 16.9 kph wind and AQI 65.

Regulars describe near-perfect weather most days this month, hot but the city's 800-metre elevation keeps the dry-climate heat from feeling as oppressive as the temperature alone might suggest, with rain essentially a non-issue. Our row backs both halves, 30.2C reading as a hot 31C, over 20.1C nights, with rain nearly absent, 1.7mm across under a day, and humidity down to 61 percent. Regulars are honest this still runs genuinely hot for anyone with lower heat tolerance, but the long, warm days and reliably dry skies are called a real draw rather than a compromise. The record: 11.2 hours of sun, a 14.8 kph wind and AQI 54.

Jerusalem's October threads describe warm days and genuinely cool evenings — highs near 27°C dropping to about 16 overnight — and the forum is insistent that Jerusalem gets far chillier after dark than Tel Aviv, so a sweater or fleece belongs in the bag even in a warm month. Rain is possible but unlikely: a day or two at most across the month. The real complication isn't the weather but the calendar — Rosh Hashanah, Yom Kippur and Sukkot often fall in October, bringing premium pricing and crowds, and Yom Kippur shuts the country down entirely.

Regulars set expectations for a week here rather than a month: perhaps one properly wet day, a few showers, and three or four dry ones - far more sun than rain, and never for long when it comes. Our 39.5mm across 6.9 days is that arithmetic scaled up, a little over one wet day a week. On temperature they warn that this city is in the hills and cools sharply after dark; our row reads 20.7C by day and 13.5C at night, feeling 19C and 12C. Layering is their word for it - more in the morning, less by noon, more again in the evening - with a light rain jacket rather than a winter coat. The record: humidity 64 percent, 9 hours of sun and AQI 62.
