July is high for San José.
July often brings a welcome midyear break in the rains — the 'veranillo' (little summer), a short drier spell that can run roughly through parts of July. Temperatures stay steady near 26°C/17°C, and rainfall eases compared with June (about 180mm).
This makes July a popular month despite being green season: the partial dry spell brings sunnier days, and it coincides with the Northern Hemisphere summer holidays, so visitor numbers and some prices rise from the May-June low. It's a good balance of decent weather and not-quite-peak crowds.

San José in July — Full Picture
July often brings a welcome midyear break in the rains — the 'veranillo' (little summer), a short drier spell that can run roughly through parts of July. Temperatures stay steady near 26°C/17°C, and rainfall eases compared with June (about 180mm).
This makes July a popular month despite being green season: the partial dry spell brings sunnier days, and it coincides with the Northern Hemisphere summer holidays, so visitor numbers and some prices rise from the May-June low. It's a good balance of decent weather and not-quite-peak crowds.
Mornings remain the safest bet for clear volcano views and outdoor activities. The Caribbean side and Tortuguero are appealing now, with sea-turtle nesting underway on that coast.
The weather is still unpredictable — the veranillo isn't guaranteed — so pack a rain jacket and quick-dry layers, plus a warm layer for the cool cloud forest and volcano summits, and insect repellent for the lowlands.
What to Wear & What to Pack
Green season with a short drier spell — around 26°C/17°C. Clear mornings, lighter afternoon rain than June. Rain jacket and quick-dry layers. Warm layer for the highlands.
