The month in which extreme heat shapes the future.
You arrived in Trás-os-Montes in July and this is what you see: a biting heat, a silence that is almost noise, and an olive grove that seems empty—not of life, but of water.
July is the driest month for the olive grove. It's not a month of visible action. It's a month of waiting, anxiety, and observing how tiny olives—the size of a grain of corn—cope with a brutal reality: temperatures above 35°C, a total absence of rain, and all the water the tree needs has to be extracted from the soil.
It is in this water stress that good and bad harvests are defined.
July in the olive tree cycle: development under pressure
The tiny olives that formed in June and early July are now in a phase of intense development. Under ideal conditions, they grow rapidly. But in July, in Trás-os-Montes, the ideal conditions disappear.
Ideal temperature for olive growth: 10-30°C. Above 35°C, growth begins to be compromised. (OlivoNews)
In July, especially during years of extreme heat, temperatures can regularly exceed 35°C in the interior of Trás-os-Montes. When this happens, the olive tree—which evolved to survive in Mediterranean conditions—activates protective mechanisms: it closes its stomata (small openings in the leaves) to avoid losing water. But this comes at a price: photosynthesis is reduced, energy production decreases, and the tiny olives grow more slowly. (Agrotec)
The absence of rain in July is practically total. All the water the olive tree receives comes from irrigation—or it doesn't come at all. In rainfed olive groves (the majority in Trás-os-Montes), drought is a real risk factor. A dry July can significantly compromise the September/October production..
Why July is special for visitors
For the contemplative observer:
July is the most arduous month for the olive grove — and also the quietest. Without the activity of harvesting, without the frenzy of flowering, the olive grove in July is a space of waiting. The trees are focused on surviving the heat and developing the fruit with the water they have.
The landscape is arid, yes — but a beautiful aridity. The interior of Trás-os-Montes in July offers shades of greyish-green (the leaves wrinkle slightly under water stress), a deep blue sky, and a luminosity that few territories in Portugal can offer. It is the beauty of the extreme..
For the photographer and artist:
July is the month of direct light, of sharp shadows, of precisely drawn landscapes. The tiny green olives against the grey-green foliage create a unique visual theme. The early morning hours, when there is still moisture in the air, offer extraordinary compositions.
For those who want to understand fragility:
July is when you understand that olive growing is not a guaranteed activity. An entire harvest—the result of 12 months of work—depends on how hot it is in July, how much rain falls in August, on factors completely beyond human control..
What to do in July: itineraries for warm weather and beautiful scenery.
Basic Experience: "Aridity and Growth" (3–4 hours, early morning)
Dawn walk through developing olive groves — observe the tiny olives, understand the water stress, and perceive how the landscape completely changes compared to June. The goal is to be in the olive grove between 6 and 10 am, before the extreme heat.
Ends with coffee and a conversation with a producer about the anxieties of July. Contact producers at azeiteanorte.pt/en/produtores.
Itinerary: "Inland Summer Landscape" (full day)
Morning: walk through olive groves. Midday: rest at a shady farm (with fresh water!). Afternoon: route through viewpoints in Trás-os-Montes overlooking the Douro Valley — the July landscape is arid, but spectacular. Focus: photography, contemplation, understanding fragility.

For travelers sensitive to heat:
July is the most climatically demanding month. If you prefer moderate temperatures, choose May, June, September, or October. If you come in July, come prepared: constant hydration, extreme sun protection, and the understanding that heat is part of the experience.
When to go in July: a practical guide
Time | What to wait for | Recomendation |
1–10 july | Beginning of water stress; olives still small | Good — there is still some water in the soil |
11–20 july | Maximum water stress; arid landscape | Ideal for photographers; more contemplative |
21–31 july | Continuous stress; desert landscape | Good — fewer tourists; extreme landscape |
Important note: Temperatures in Trás-os-Montes in July can regularly reach 35-40°C. Confirm weather forecasts and the condition of the olive grove with a producer before visiting.
Water in July: the critical factor
In July, water is everything. The olive tree is a drought-adapted species—it has deep roots that explore deep layers of the soil, small leaves with a thick cuticle to reduce water loss, and small stomata on the underside of the leaves. (OlivoNews)
But adaptation has its limits. An extremely dry July, without any irrigation, can compromise the entire harvest.
That's why conversations with olive growers in July are always about water: is there irrigation? How much? When? Is it enough?
If you visit a producer in July, you will hear this anxiety. It's real. It's because it matters.
July in the villages of Trás-os-Montes
July is the month when the rural villages of Trás-os-Montes enter an almost complete pause. The heat keeps people indoors during the day. At night, they climb stairs to get some fresh air on the terraces of the taverns, in quiet conviviality.
Culturally, July marks the end of the "intense work" phase and the beginning of the waiting phase—until September, when the harvest approaches.
July's cuisine is light: salads with cured olives, grilled fish, fresh vegetables. All accompanied by water—lots of water. And olive oil, of course, always olive oil.
July: the month nobody looks for, but that matters
July in the olive grove doesn't have the drama of May (flowering) nor the activity of October (harvest). It has silence, extreme heat, and the raw fragility of a plant surviving.
If you only come to TMAD during the "nice" months, you miss this: the month when you truly understand what it means to depend on nature. The month when you see a small green olive, still the size of a grain of corn, and think: "In 3 months this will be an olive; in 4 months it will be oil; next year I will still be drinking the oil this tree makes now, in this extreme heat, with water stress."
July is a concentrated cycle. It's the future being decided.
🫒 Mark the date in July. Get in touch with a producer. Come and observe the aridity.
