Best time to visit Leiria

June is the best month in Leiria, scoring 92 out of 100, with January the weakest at 60. The 32-point spread means timing is worth planning around without being decisive. The good window runs May to September — 5 months within ten points of the best.

August is the warmest month at 30.2 °C and January the coolest at 14.9 °C — a 15.3 °C spread across the year. Around 49 days a year top 30 °C, concentrated in August and the months either side.

There is a real wet season here. January, March, October, November and December carry the rain — up to 13 wet days in a month — while June to September drop as low as 2. That 11-day gap is the biggest single difference between a good month and a bad one in Leiria, and it moves further than the temperature does.

The sea peaks at just 19.9 °C, which is wetsuit territory even at its warmest — a coast to look at rather than swim in. Daylight runs from 9.4 hours in winter to 15 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are June, May, July. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
