Not sure what the temps are in La Manzanilla but here in Kamloops we are frying. Yesterday we hit 41celcius. Suppose to be like this for up to five days. Oh where is the ocean when you need it. Four more months and counting.

Right now it is 90 F inside, so I'm sure it's hotter outside.
The ocean must be at least 85 F, but it is clear and, relatively, refreshing.

And for your more scientific folks, that converts to 315.15 Kelvin

Wow, that's some heat wave you're having Evelyn: 25°F / 14°C above normal! At least you're having desert-like low humidities to keep your heat index (or "feels like" temperature) down.
According to the Weather Underground's weather data from the Kamloops airport ( http://www.wunderground.com/history/airport/CYKA/2014/7/13/DailyHistory.html? ), they had an afternoon high temp yesterday of 105°F / 40.6°C, sometime around 5 or 6 PM (there is an irregularity in the data.) At the same time, the relative humidity was 8% or 9% (disregarding the anomalous data point.) Combining the temp and RH gives a heat index of 99°F / 37°C. (It's common in dry locations to have a heat index lower than the temperature. It's very common in Phoenix, AZ where I'm from.)
You might be glad you DON'T have a warm ocean next door, at least in the summertime. The Pacific brings us copious humidity. Here at my place in La Manzanilla, yesterday's afternoon high temperature hit 96.3°F / 35.7°C, and at the same time the relative humidity was 55%, yielding a heat index of 113°F / 45°C. That's what it "feels like" here in the afternoon, in the shade, in calm air. And for those of us without air conditioning, it's about the same inside and outside.
Our afternoon highs only tell half the story. Our nighttime lows are also quite warm and muggy, making it challenging to get a good night's sleep sometimes. To blame are the powerful thermal mass of the nearby Pacific combined with the nightly (and very annoying) "debris clouds" left by the thunderstorms that usually peter out before giving us any cooling rains. This thick overcast traps the day's heat like a greenhouse, preventing the radiation of the heat out to cold space.
So a typical nightly low temperature here in my back yard this time of year is 82°F / 27.8°C, with a RH of 77%, for a heat index of 88°F / 31°C.
Contrast this with yesterday's Kamloops nighttime low temp of 61°F / 16°C, with a RH of 56% (heat index is not valid at this temperature.) Even in winter, the nighttime lows hardly ever get that cold in my back yard here in La Manz!
Anyway, here's hoping we all get some relief soon. It's 11 days and counting since our last cooling rains here in La Manz.

Bret, you are so good with your reporting. Very interesting and love to read all your info. Thanks . Ottawa, Canada is having some weird weather too. Summer one day and spring the next. Very strange.

Up here in Spudville the daytime highs have been over 100F with the lows around 70. RH is single digit to low teens. Rain would be nice, instead we get dry thunder storms with plenty of lightning.
Just yesterday we watched a smoke plume grow from a couple of fires about 10 miles to the northwest. This morning we are smoked in with visibility down to a couple of miles.
An ocean to go jump in would be a nice relief, maybe it's time to head south? See ya, Rojo

Just have to report 114F.yesterday in SAcramento and Chico, California. Humidity about 40% and nighttime low about 80F.

Well down here in Leamington, Ontario the most southern tip of Canada, it is cold! Morning temp of 15C or 61F, but oh going ALL THE WAY UP TO 70F this afternoon. Gee maybe I can take off the wool socks--NOT!!
Just a weird "summer" all around I guess.

I love Bret's keeping us aware of storms, rain, etc.
But I do have an issue with the temp X relative humidity to equate to a "feels like" temperature.
In the central valley of California (Sacramento, Chico, etc.) we often get temps well over a 100 F. At those times, going outside is like stepping into a furnace.
Here, in LM, no matter what the temp or the humidity, it's simply a steam bath. Rains are nice, fans are crucial (so power outages are the worst)and though our house has air conditioning in the bedrooms, the only time I wanted it was when the power was out a few weeks ago.
Bret, you're welcome to come over and sit under the air conditioner in the guest room (assuming that the power is on).
It's all relative when it comes to heat.
